Achievements Dupe Mod
by CriminalPear
Achievements Dupe Mod lets players spend advancement-based tokens to copy the item they are holding, with one token earned per completed advancement.
What it does
Each completed advancement becomes a dupe token, and a token is spent to copy whatever item is in the player's main hand. The copy drops on the ground. A menu opened with the Right Ctrl key shows how many tokens remain and how many have been used in total, so the same progress cannot be spent twice. Once tokens run out, more achievements have to be earned.
Each player keeps a separate balance that stays with that player, which works on singleplayer worlds and on servers. The balance refreshes as soon as the menu is opened, and advancements completed earlier count toward it. The mod is client and server, so the server and every player need it. Builds cover 1.21.11 – 26.3 on Fabric and NeoForge under All rights reserved, and the code is not open source. Fabric Loader and Fabric API are required on Fabric, and players use the file that matches their Minecraft version, with a 26.x build covering later 26.x releases.
Key features
Advancement tokens
Every completed advancement adds one token, so progress in the game directly sets how many copies can be made.
Held item duplication
Hold an item in the main hand, open the dupe menu, spend a token and the copy drops on the ground beside the player.
Usage tracking
The menu shows tokens left and tokens used in total, which prevents the same progress from being spent twice.
Per-player counts
Each player keeps a separate token count, so the feature works in singleplayer and on multiplayer servers.

Ever earned a stack of achievements and thought "cool, but what did that actually get me?" This mod gives those achievements a point. Every advancement you complete becomes a dupe token, and you spend those tokens to copy whatever item you're holding. That's the whole idea. Play the game, unlock things, and cash that…
