by PrxjX

PrxjX's Xp Optimizer is a Fabric client mod that automates throwing Experience Bottles while the use button is held down.

FabricClient-side onlyAll rights reserved1.21 – 1.21.11

What it does

Holding the use button throws Experience Bottles repeatedly, replacing manual clicking when collecting XP for enchanting, repairing gear with Mending, or farming. The throw rate is set by a CPS slider that goes from 1 to 100 clicks per second, with 8 CPS as the default, and the bottles can be thrown anywhere.

Only the client needs the mod, so it can be used in single-player or on a server without the server installing anything. Builds exist for 1.21 – 1.21.11 across 12 release versions, and the latest Fabric file is 1.0.0 for 1.21.11. The code is released under All rights reserved, so it is not open source.

Key features

  3. In-game configuration
