Book and Quill Dupe Code

This page demonstrates the utilise of a bug to make a contraption.

Bugs of this nature may exist stock-still at whatsoever fourth dimension without warning. When this happens, the contraption will end to work.
Utilise at your ain risk.

This page seeks to teach you lot how to clone items and blocks without building a separate farm for them, in vanilla Survival mode. Information technology tin exist treated as an "everything farm," since information technology can "farm" things that tin can't normally be farmed, like block of diamonds, dragon eggs and other non-renewable blocks.

If any of these do get patched, y'all must either go back versions or use 3rd-political party applications in order to replicate them again. For Java Edition, this can happen in the Minecraft Launcher, simply on Boulder Edition, yous must utilise 3rd political party applications in order to replicate these once again. These third-party applications are NOT endemic or endorsed by Mojang, then employ at your ain adventure.

Note that these techniques are considered "cheating" by many people and Mojang tries to remove the ability to indistinguishable in Survival during almost every update. On some servers, these techniques are bannable offenses.

The best mode to duplicate a cake is to turn it into an item first, then duplicate the detail. However, in that location are other ways to duplicate the blocks themselves, though they simply work for sure blocks. Shulker boxes brand particular duplication much easier because they allow for up to ane,729 items to be cloned at one time (including the shulker box).

Uses [ ]

• Duplicate your most valuable gear: if you lot lose them to lava or the Void, y'all tin just pull a backup from your backup chest! More than specifically, you make a duplicate from your backup, so you tin go through the entire process if y'all lose them over again.
• Indistinguishable Enchanted Books / Diamonds / Ancient Debris / Netherite Ingots / Emeralds: In one case you take ane, you'll have an infinite amount by duplicating it. Again, information technology is of import to leave some stock equally backup; you never know if you need more.
• Duplicate Enchanted tools / Blocks: You'll never have to worry well-nigh running out of your tool / block of option, since yous can but duplicate them besides. Duplicate in bulk for items/blocks that will be used in big quantities.
• Duplicate Shulker Boxes (with items inside): theoretically you can duplicate both the shulker box and the items information technology contains, since that info is stored inside the shulker box itself. Utilise this to duplicate blocks in excessive quantities.
• Duplicate Enchanted Equipment: combined with a grindstone, you can farm an infinite corporeality of EXP by removing enchantments from duplicated enchanted gear. While a decent, safe and consistent method of getting exp, edifice an Enderman Farm is faster.
• Infiltrate Pay to Win servers (Not Endorsed): Servers that violate the EULA by selling in-game items for real money can be duped and sold. Duping the most valued items and distributing is the most effective. Duping is considered cheating and tin become y'all banned on multiplayer servers. Most of them usually patched these dupes using Third-Party plugins.

If yous happen to exist a speedrunner, duplication if allowed can cutting down a lot in your game time. One extreme example is the TAS Any% speedrun done in 29.xix, complete with the dragon dead. Alt+F4 is usually used for this purpose.

Legitimate Duplication [ ]

These are non actually duplicating items, merely instead are legitimate (or generally legitimate) methods of obtaining certain items.

Clay Duplication (Both editions) [ ]

Start past obtaining at least 2 dirt and gravel from bartering. Next, craft coarse dirt using 2 dirt and 2 gravel for 4 coarse dirt, then till the dirt and mine it to obtain ii extra dirt. With a bartering farm, a good hoe, and a proficient shovel, y'all can mass produce dirt in a matter of minutes. Notwithstanding, this is not perfect duplication, as you will need a abiding supply of gravel.

Infinite villager trading i.16+ (Multiplayer only) [ ]

This is known to piece of work in vanilla one.16.5, but has been patched in Paper. Sure items can be obtained abnormally speedily from villagers at only a small price of a very arable tradeable resource (like sticks). Yous need to create a infinite zombie villager station.

Java Edition [ ]

Unpatched/Working [ ]

Currently, work as of the latest release of vanilla Minecraft. They may be patched in modified servers (such equally Spigot, or Paper), which many servers employ, just have been tested and they still work in unmodified conditions. In singleplayer, these volition work merely in multiplayer, these will usually not work.

Singleplayer [ ]

Basic Save File manipulation [ ]

This method is safe and reliable. Needs merely the desired items for duplication also as a chest. Y'all need to accept admission to save files and so this is impractical on servers, where admins aren't giving FTP out like candy.

1. Take the desired items to exist duplicated on y'all: whether it's in your inventory, on your hotbar or equipped doesn't matter.
2. Exit and save the game - returning to the primary card is quickest.
3. Navigate to your save folder. On Linux, this is located at ~/.minecraft/saves, on macOS it'south at ~/Library/Application Back up/minecraft/saves, and on Windows, it's at %appdata%\.minecraft\saves.
   1. Making a backup folder of the target globe binder is advised but unnecessary.
4. Open the target world folder and duplicate the level.dat and level.dat_old files.
   1. Information technology is advised you keep the duplicates in a place piece of cake to admission, usually the world salve binder itself. This especially applies if y'all programme to duplicate items multiple times.
   2. Alternatively, take multiple folders on screen to only select, re-create and paste from one to another.
5. Enter the target globe and deposit the desired items to be duplicated into a breast.
6. Exit the world and return to the main bill of fare; the game should save.
7. Re-create and paste the duplicated level.dat files dorsum into the target world folder.
8. Enter the target world. The desired items should both be in the inventory and in the chest.

Extra info: these files also comprise your electric current location and your exp. Theoretically, you tin enchant some gear, deposit information technology in a chest, then load the level.dat file to preserve your level and proceed the enchanted gear. Another potential use is to employ up your inventory while building then load a fill-in to keep your progress and refill your inventory with the building cloth. You could fifty-fifty use this to try multiple times to kill the Ender Dragon / Wither without risking your gear and inventory.

Disclaimer: the environment and mobs are not saved with this method, do not attempt to summon the Wither near places of importance or important mobs. Instead, backup the unabridged target world folder and load it in event of failure. Perform test runs to ensure that this method works.

Alt+F4 v2.0 - Task Manager [ ]

Alt+F4 is patched, simply using Task Manager to end the task, on the other hand, is Not patched, and still works. This is very similar to the Alt+F4 method. Steps:

1. Open chore managing director
2. Get into the world yous desire to gull the items in
3. Brand certain 'Pause on Lost Focus' is off - Do this past pressing F3+P until you see something like "[Debug] Pause on lost focus: disabled" in conversation
4. Put the items that you would like to dupe in your inventory
5. Close the world and open it up once more
6. When it loads drop the items on footing by pressing 'Q' on the item. Don't close your inventory.
7. Quickly press ALT+TAB or CTRL+SHIFT+ESC to get into Task Managing director
8. End the process "Java(TM) Platform SE Binary" or "OpenJDK Platform Binary"
9. Open Minecraft and load the world again
10. Collect your items

From testing, it doesn't always work. Endeavour playing with unlike timings.

Unknown/Unpatched (SP and MP [may exist patched on MP]) [ ]

Unpatched i.16.5 MULTIPLAYER duplication (Explosive fireworks + elytra) [ ]

This duplication glitch works on 1.sixteen.5 multiplayer. It requires an elytra and firework rockets that bargain harm to the player. If the rockets do not damage the player, the duplication will non work. Video beneath: (duplication glitch starts at 0:33)

This is known to work in vanilla servers and realms, however Spigot has patched the problems and Paper has patched it long before its discovery.

Clay Duplication [ ]

The mechanism for growing giant bandbox trees is known to be glitched in JE 1.16 snapshot. Instead of growing a giant tree on the saplings, the game grows the tree on the first position where infinite is sufficient and a dirt cake is nowadays in the n-due west position. When the tree is grown, all the dirt blocks are filled in. With bone meal and piston automation, a semi-motorcar dirt duplicator can be produced (YouTube by ilmango).

Lead Duplication(note: does not work in ane.16.4) [ ]

Bring an animal to the end, put a atomic number 82 on it, and then atomic number 82 it into the finish portal. When yous get back, it should take dropped two leads. Sometimes one of the leads ends up in the end, and then make sure to check there. It may not always be in the finish, though. This also works when bringing animals into the nether.

ALL Item Duplication Glitch (Patched on spigot & paper) [ ]

This duplication glitch works on Singleplayer and Multiplayer. All you have to practice is identify a chest in front of you and and then leave the server equally information technology saves your player data, and then relog and put the items you lot want to dupe from your inventory in the chest, get a book and quill, overload the book with excessive characters and it will cause you to get kicked from the server and rolling back your player data to last salvage while server files stay the aforementioned. Every bit a consequence, the items will be in both your inventory and the breast. (requires fabric download and custom download to work) Video hither: https://youtu.be/ml3HkqNfUH4

Carpeting Duplication Glitch (Patched on paper) [ ]

This glitch gives infinite fuel and is very easy to automate give thousands of carpets per hour tutorial: https://www.youtube.com/watch?v=mGQLDJ8dNGs

Dragon'due south Breath Duplication [ ]

Whenever the dragon lands on the stop portal and releases the imperial fog, exist in a higher place or below the purple fog, look at the fog at a steep angle, and go along to harvest the dragon's breath. The fog will first shrink as intended, but afterward it reaches the smallest size, information technology will expand with each bottle used, and keep expanding until the fog disappears as too much fourth dimension passed. (YouTube by Underscored Frisk)

Block Duplication [ ]

Unpatched [ ]

Book Mod (Patched on Newspaper) [ ]

Similar to the Chunk Dupe, but rather overloading the player data. the book modern is a mod that automatically fills the book that volition overload the histrion'south information. once leaving, the data wont save causing histrion data to be reverted!

Using Shulker Boxes (Patched on spigot) [ ]

Shulker Box dupe allows you to indistinguishable whatsoever item in Minecraft singleplayer or Realms. This glitch works with two players or with an automobile mine mod. So y'all rapidly spam your item in and out while information technology beingness broken. The fundamental is to take the item out but earlier the shulker box breaks. This may have a few tries just eventually you lot will dupe your items.

You can besides use autoclicker with these settings: time between clicks- 1sec 487milisecs. Then you bind the autoclicker to central n, and automine to key m and press north,m,right click at the same time. This opens shulker. Hover over item you want to duplicate - shulkerbox should break and item in it, and particular on the ground.

Rug Duplication [ ]

Carpets can be duplicated using a contraption made of 2 Slime Blocks, a Viscid Piston, and an Observer. This method works for singleplayer and multiplayer. Video here https://www.youtube.com/watch?v=mGQLDJ8dNGs

Patched (Paper) [ ]

These detail duplications work in vanilla servers and Realms, simply many servers use a modified server software called Paper for many reasons, including swiftly patching many exploits. Here are many cake duplication methods that will non work on recent builds of Paper but work fine in vanilla.

Rail/Carpet Duplication (Unpatched in Newspaper Build #358) [ ]

https://www.youtube.com/lookout man?5=U-9ihB7EmKI and https://www.youtube.com/watch?v=mGQLDJ8dNGs&t=3s are in-depth tutorials that testify how to exercise and so

TNT Duplication (Patched in Paper 1.fifteen.2 Build #350) [ ]

TNT duplication works in a similar way equally rails duplication. A TNT block is BUD-powered, such that when the contraption is pushed by a piston, the TNT is updated and ignites into a primed TNT entity. And then, the piston moves the TNT from the list of TNT block left. This doesn't and then much duplicate the TNT block as information technology creates free primed TNT entities from it without deleting it. Many TNT duplicators all the same piece of work, but unless properly constructed will blow themselves upwards. TNT duplication is unreliable and will fail sporadically. This appears to have been patched in version i.sixteen.4 ^{[ verify ]}

One mutual TNT duplication design uses a minecart on a detector rail to power the slime block it is placed on, and moves a TNT block next to a coral fan underneath, the combination of the TNT and the coral duplicates the TNT whenever the whole contraption is moved forwards with a piston. For an indepth tutorial of this one checkout Cheesysponges video https://youtu.be/3Izrj2m6Li4

The 2d slice may exist placed on either side, and the coral fan has been marked with vines. To prime the mechanism, the upper slime blocks must get-go be moved forward, pushing the TNT nether the runway. Afterward this, moving the whole assemblage frontwards with a piston will duplicate the TNT, spawning a lit TNT entity direct below the TNT block.

Gravity Block Duplication (Patched in Newspaper i.fifteen.2 Build #358) [ ]

At that place are many ways to do this, but the basic idea is the aforementioned.

A gravity-affected block is pushed toward an end portal. It becomes an entity as information technology falls into the portal, and it travels into the other dimension's "spawn indicate.", only before it's removed from the original dimension, it bounces off an entity in the portal (in a vehicle so information technology won't become through), and is caught past some pistons. It so turns into a block and is returned to its original location. This procedure can be looped using redstone. It works for any block that is affected by gravity, except for primed TNT because information technology would blow upwards the contraption and cannot get a block over again in whatsoever instance.

Dragon eggs and anvils autumn differently from each other and other gravity-affected blocks such as sand, gravel, and concrete powder. Neither dragon eggs nor anvils work in a sand/gravel/physical powder duplicator considering of this. Still, it is possible to create a machine that can duplicate dragon eggs and anvils merely not sand/gravel/concrete powder. They both can be duplicated and sent into the Terminate equally either falling entities or items.

Tripwire Hook Duplication (Works vanilla 1.16.three) (Patched on Newspaper) [ ]

Tripwire Hooks are duplicatable, but only in certain directions. Information technology may work in some directions, just non others.

Patched/Non-Working [ ]

These no longer work equally of the latest release of vanilla minecraft, just worked on older versions.

Singleplayer [ ]

These are dupes that only work(ed) on singleplayer, either considering you need access to manage the server, Newspaper/Spigot patched it, or almost servers have plugins that allow it not work.

Alt + F4 Method (Patched i.xiii) [ ]

This method is a simple method and has been around since the get-go of the Blastoff stage. This method involves dropping the items yous desire to duplicate, and then saving and quitting. You would and then reload the world, pick upward the items and press the keyboard shortcut to close a window. And then relaunch the game and reload the world. The items should be duplicated.

Multiplayer [ ]

These are dupes that merely work on multiplayer, usually considering they exploit an anti-dupe plugin (like the thousands of ass dupes)

Deadly Method (Patched 1.15) [ ]

This method is extremely deadly, but non necessarily to the player. This method involves taking a mob that can carry items (due east.g. a zombie, a ass or a llama) down to very low health (i.due east. half a heart or less). Using extremely precise timing, impale that mob as information technology travels through an terminate portal or nether portal. The items equipped and the mob should appear in the other dimension. Information technology works by tricking the game into thinking the mob is alive on one end of the portal and dead on the other side. The live mob volition travel through the portal nevertheless conveying the items, and the expressionless mob's items are also sent into the portal, allowing the player at the other terminate to collect the cloned items and the mob carrying them.

The deadly method used to automatically farm diamonds (currently the fastest theoretical means of automatically obtaining items in vanilla survival):

Same Role player Twice (Patched in nigh every server) [ ]

In that location is a way to trick the game into logging in the same histrion twice on 1 server. To exercise this, start two instances of Minecraft. This requires starting a new instance of the Launcher so that they don't interfere with each other. Log them both on the same server at the same fourth dimension. By doing this, the game will render two of the same player. You can and then kill the copied player and double your inventory. Rarely servers may also duplicate players on accident or go out "ghosts" of logged out players which can be killed for the aforementioned event.

Ass Inventory Oversight (Patched in 20w16a and in Newspaper/Spigot 1.15.ii) [ ]

Working in 1.15.two and in 1.16 snapshots up to 20w12a (Patched in 20w16a and in paper). Yous need a tamed donkey or llama equipped with a breast. If a player shift-clicks the donkey / llama, that player may view the ass's inventory and place items. If a second histrion rides the donkey, the first player will continue to view the donkey's /llama'southward inventory, even though it is non normally possible to view a donkey's inventory when it is already being ridden past a player. If the second player disconnects, the donkey will disappear along with them, and the donkey's inventory will be considered by the game equally role of that player'southward data. Yet, the game will proceed a re-create of the donkey'south inventory and GUI temporarily loaded for the first player, who can then reclaim the items. When the 2nd player reconnects, the donkey's inventory will contain what was originally in it before the second player disconnected. The items can once again exist taken from the donkey's inventory, resulting in x2 duplication.

Both [ ]

These dupes work(ed) everywhere! Servers that don't use anti-dupe plugins, singleplayer, etc.

Bundle Duplication (20w45a to 20w48a) [ ]

For any crafting recipe that uses more than 1 of the same detail, y'all can use this dupe. To apply it, you put the items in the crafting grid, then employ the bundles on the crafting slot. The resulting item will non disappear simply you volition save the item you just took from a bundle. For case, if you used 9 stacks of netherite ingots to make 1 stack of netherite blocks, y'all could use ix bundles to take all the netherite away and go 1 stack of netherite blocks for no cost.

Baby Piglin Particular Dupe (Patched in i.16.3) [ ]

This dupe involves infant piglins. It is incredibly unproblematic and information technology works in multiplayer. To perform this glitch notice a baby piglin and drop his health downwardly to a 1-hit kill (ii hits with a normal diamond sword should piece of work). Then drib the item you want to indistinguishable to the piglin(e.g. a shulker box) then expect for the babe piglin to selection it up. After the piglin has picked up the item drop the piglin 1 gold ingot. While the piglin is admiring the gilded, kill the piglin.

Zombie/Drowned Method (Patched) [ ]

This method exploits the fact that zombies can transform into drowned while they are dying. If you coax a zombie to option up an item by throwing one at it and so kill it right at the moment that it converts to a drowned, the zombie will die and drop what it was holding but the newly spawned drowned will be holding a duplicate of the particular. This can also work with husks transforming into zombies.

Ilmango shows a simple implementation for survival:

Chunk memory overflow (Patched 1.15) [ ]

When you lot overflow clamper memory, y'all volition exist able to freeze clamper. What this ways is that changes on this chunk will not be saved and afterwards loading it again it volition render to the previous state. The best style to practice this is to create books filled with about l pages of random Unicode characters and put information technology in a chest. There are mods for doing this automatically, just you can also do information technology manually by copying and pasting. You volition need two different types of books for this to work.

1. Choose a clamper in which you want to duplicate and do everything only in this chunk (Press F3 + G to meet chunk borders).
2. Get 22 books filled with random characters, name them "X" and 21 filled books but with other characters, proper name them "Y".
3. Place a chest and put the items you want to duplicate inside information technology.
4. Place a chest at the same chunk and put them in this pattern:

   X|Y|X|Y|X|Y|X|Y|X

   Y|X|Y|X|Y|10|Y|10|Y

   X|Y|Ten|Y|X|Y|X|Y|10

   • You will have 8 books of each type left.
5. Place a chest above it and put 8 of volume Ten in slot 1 and 8 of book Y in slot 2 in that chest.
6. Reload chunk past reconnecting to the world(if yous are on singleplayer) or going 200-300 blocks away and returning(if you are on multiplayer)
7. Movement books from the 2d chest similar this:

   Ten|Y|X|Y|Ten|Y|X|Y|X

   Y|X|Y|X|Y|X|Y

8. Accept out the items y'all wanted to indistinguishable into your inventory or put them in a chest at the other chunk.
9. Reload chunk again.
10. Now you have your item(south) in the chest and in your inventory. Books in a 2nd chest are simply similar in [four].

In 1.14+:

1. Press F3+G to run across the clamper border.
2. Place a barrel in the chunk that y'all want to duplicate. Then, place a breast to a higher place information technology.
3. Then, put the items that you wanted to duplicate in the barrel.
4. After that, put 25 volume and quills that filled in with 100 pages of random unicode characters in the chest similar this.

   X = 1 book; Y = stack of 2 books

   X|X|X|X|X|X|X|10|10

   10|10|Ten|X|X|X|X|10|X

   Ten|Ten|X|Ten|X|Y

5. After that, printing esc and select 'Save and Quit to championship' to relieve the clamper (If you're in singleplayer) or walk 400 blocks away from the chunk (If you're in multiplayer, brand sure of the other players were stayed in the under else the duplication won't work). This method will relieve the chunk.
6. Then, log-in your world again (If you're in singleplayer) or walk dorsum to the clamper (If y'all're in multiplayer).
7. Open the breast and movement the books like this:

   10|X|X|X|X|X|10|X|X

   X|X|Ten|X|X|Ten|X|10|10

   X|X|Ten|X|X|X|X

8. Take your items away from the barrel and move them to your inventory or put them in a barrel at the other clamper.
9. Save chunks again.
10. Become dorsum to the clamper over again.
11. Your items will reappear in the barrel. The books volition be reverted to the country in step 4. Duplication complete.

Dropped Items (patched 1.13) [ ]

Relogging at the same time as you drop items can dupe items. Needs very precise timing; exit the 2d you see the items but before you lot hear the audio of collecting items.

Piston Duplication (patched 1.xvi) [ ]

When an item frame is removed (broken by the player) from the rear of a piston every bit the piston is retracting, the right timing volition yield two items of the item that was within the frame. This will piece of work with any blocks or items inside of the frame, with shulker boxes existence able to duplicate multiple items at once. This method works in both singleplayer and multiplayer game modes.

Crafting Dupe (Patched i.12.ane) [ ]

1. put 2-three stacks of planks in your inventory.

2. driblet the particular you want to gull on the footing( make sure that in that location is no particular that it can stack within your inventory)

3. open your inventory and spam the crafting tabular array recipe until you option up the particular you dropped. Information technology should result in a stack(fifty-fifty for non-stackable items)

Using Dolphins(Patched one.17-pre2) [ ]

Put a dolphin in a nether portal equally it absorbs an item. The original item will still exist there, while the dolphin will comport a copy.

All Particular Duplication Glitch (patched i.17.ane) [ ]

Make full your inventory with items. Repeatedly rename the detail you want to duplicate on an anvil until the anvil breaks. When it does, y'all volition drib double the renamed item.

Dirt Chest (works 1.16.i+) [ ]

When using this method there might be a chance the items will get deleted, and so creating a backup is recommended. This method will not piece of work on Realms.

1. Gather all the items you lot want to duplicate as well as a chest.

ii. Identify your chest, and make sure in that location is 4 dirt in forepart of the chest.

3. Save & Quit, and then rejoin the World.

4. Place the items you desire to duplicate in the chest and quickly intermission four dirt in front of the chest 1 y-level beneath information technology in a 2x2 square shape then count to 4.

5. Rapidly forcibly close the application.

six. Rejoin the game. One of three things will have happened; A) The items will have duplicated (both in inventory and chest), B) The items volition accept been removed (neither in inventory nor chest), C) Nothing will have happened (in breast or inventory).

Chunk save stating [ ]

This method works by causing the game to crash in a fashion that only the chunk you are standing in will not save correctly, this volition cause the clamper you are standing in to revert to the last save, allowing you to gull in that chunk.

This duplication is no longer possible on realms and merely works with stackable items.

ane. Become a buoy (It does not have to be activated).

two. Put items to indistinguishable in your Hotbar, the nine slots on your screen.

3. Open up the beacon GUI.

4. Double-tap on the items yous want to duplicate. Y'all can't duplicate non-stackable items, and it only duplicates up to fill a full stack.

Note: This might only piece of work if Settings > Video > UI Profile it is set to Pocket, non Archetype.

Fortune on Flowers [ ]

This can be used to duplicate whatsoever 2 block tall blossom and tin exist considered by some as legitimate duplication, since the bug tracker says it works as intended.

Steps:

ane: Get an item with Fortune (level three works best) and a ii block tall flower.

2: Place the 2 block tall bloom.

3: Break said flower.

The flowers should have at least duplicated. I recall you can become upwardly to vi!

Patched [ ]

To use the post-obit methods, you will have to either not update past that point or revert to a previous update (if possible for your system, non all can, such as on Xbox One or Nintendo Switch).

Gravity Block Duplication (Patched on 1.16.200) [ ]

Duplicates all gravity-affected block except dragon eggs

This video will explicate how to indistinguishable any gravity-affected block. It works similarly to gravity block duplicators in Java Edition: by having a falling block enter an end portal and get a block on the same tick.

The reason this design does not work for dragon eggs is that it relies on pistons existence able to button blocks into their original position. This allows for the block to exist duplicated repeatedly, every 6 redstone ticks. However, one can manually indistinguishable dragon eggs with a similar process:

Thou	D
P

In the above diagram, the G, D, and P denotes the grindstone, dragon egg, and portal, respectively. The repeater is necessary for the timing to work correctly, due to MCPE-15793. Like the automatic gravity block duplicator, 1 must utilize huge mushrooms to replace the Finish portal frames.

To apply, deactivate the lever, and a second dragon egg will appear in The End. You can and so re-activate the lever to break the dragon egg and place another one. This design tin be used for other gravity blocks, only the automatic version is generally more than efficient.

Another culling to end portal based duping is cease gateway based duping, however, it is not every bit fast equally end portal based duping.

Anvil Duplication (Patched in 1.16) [ ]

You lot volition need ii book & quill and an anvil. Write any text in one book & quill, and sign it. From then, copy the offset book & quill by placing them side by side to each other in the crafting filigree. Accept the particular you wish to duplicate and rename information technology to the name of the copied book. From here, you tin shift-click the anvil result and duplicate your item.

Anvil Naming (Versions 1.5.one-1.16.0) (Patched) [ ]

When naming a stack of items in an anvil, you tin apply the "Take Half" option to receive the output items without depleting the original stack. As long as you do not accept the terminal renamed particular, you lot can become to the original stack and pick it up to start more or simply leave the anvil interface if y'all are done.

• A way to speed this up is to hitting "Take Half", and so "Toss Item" while standing shut to the anvil, and so you tin chop-chop go through a full stack without having to manually move each selection.

Items duplicated this way won't work for quick apply in a recipe, though certainly can be used for Archetype crafting and any other employ. Nevertheless, if y'all wish to revert an item to the default name, y'all can practice and then past crafting it into another item then crafting it back to the original (such as redstone block -> redstone dust x9 -> redstone block), or by placing it as a block and so breaking information technology back into an item.

• Sometimes a cake won't lose its proper name when cleaved into an item, such equally shulker boxes which are meant to keep their proper noun, or just randomly the name may stay with a regular cake and repeating the process will remove the name. Still, some items may break into different items, such every bit an ender chest dropping obsidian, and the obsidian will each retain the ender chest'southward name (this was likely a glitch).
• TNT Duplication
• one. Put a TNT anywhere
• 2.Put a breast aside the TNT
• 3.Put the detail that you want to duplicate in the chest
• 3.Light the TNT and at the same time the TNT explodes take out the item in the chest(this requires right timing and skilful armor if you want to stay alive later on the explosion)

Ass + Looting sword (patched 1.xvi) [ ]

ane. Go a ass

two. Go a Looting iii sword

3. Put a chest on the donkey

4. Put your items in that chest

5. Kill the donkey

The Annexation three sword causes the donkey to driblet more items than normal.

Piston Chest (Patched in 1.16) [ ]

(Duplicates all Items)

When a chest is pushed past a piston, the contents are backed upwardly a split second before it is moved. If you are in the chest interface and quick-motion an item to your inventory in that moment then you will receive the item and the breast will be moved with the item nonetheless in it as well.

The recommended build is not automatic. For the recommended build, you lot volition need at least 1 switch, 1 sticky piston, a chest, 10 redstone repeaters (all set to maximum delay), 2 redstone dust, and a push, though in that location are simpler(thus cheaper) versions that require but a sticky piston, a chest and a button. The instructions are as follows:

The "simple" method of the piston gull auto. It follows the same instructions as the more than expensive, recommended method just uses less blocks.

1. Press the push button.
2. Wait until the piston pushes the chest.
3. Open the chest, and immediately put your cursor on the cake.
4. At the last second, shift-click on the detail yous want to dupe.

The "recommended" build of the Bedrock Edition piston-chest dupe method.

If done correctly, yous should accept an identical copy of the detail you put in.

• If you can not afford to make a gummy piston, this method also works with ane regular piston on each side. I piston pushes the chest, and so you open it. You then continue as normal, shift-clicking the item at the last 2d earlier the other piston pushes the chest back to it's starting position.

• This method makes mass-duplication possible with the use of a shulker box and moving the contents of one duplicated box to the other, thus doubling how much you go each time, until yous are duplicating an unabridged box's worth of items.
  • This does run the take chances of massive lag in your world, past creating too many shulker boxes with contents. The effect may exist even greater in online worlds such as realm servers. Be sure to transfer almost items to regular chests afterward duplicating to avoid this.

Rapid Dispenser (Versions 1.five.1-one.v.two+) [ ]

(Duplicates some Stackable Items merely) (patched)

This video volition explicate how to duplicate any item that can be crafted into a block using a dispenser and a redstone clock.

Bed Duplication (Patched) [ ]

Due to how beds are fabricated out of ii blocks, an explosion nearly the bed can make the bed driblet 2 bed items, significant you can spawn 2 beds (four bed blocks) when you had 1 (2 bed blocks). You can repeat this and get infinite beds.

Ore Duplication (Patched) [ ]

Get an anvil and become either ix iron ingot, nine diamond, nine coal, 9 gilt ingot, 9 lapis lazuli, ix redstone grit or 9 emerald. Rename 1 of the ores to something random, place information technology above the rest of the ores in your inventory and go to a crafting table. Craft a cake of that ore and select 'craft all.' This will result in the thespian obtaining 1 cake of (whatever ore you lot chose). The other 8 pieces will still be in your inventory.
