Psychodreams CrystalOptimizer
by PsychoDreams
Psychodreams CrystalOptimizer changes how end crystals are placed, so that a player can set them quickly and at the exact spot intended.
What it does
The mod targets the crystal placement mechanic used in PvP. It removes the small delays that normally occur between placements, and it corrects positions where a crystal would otherwise land in the wrong place. The result is faster and more accurate crystal placement, which the author describes as making fast, precise play possible without missed placements.
Installation covers the server and each player's game. The mod runs on Fabric only, with a single file, 1.0, for 1.21.1, published 2025-10-07. The code is released under the Apache License 2.0 and is open source, and the source code and issue tracker are publicly available. The author notes that servers may allow it at their own risk and suggests pairing it with the AntiRefresh mod.

Reduced micro-delays

Accuracy and responsiveness
Placement follows the intended target more closely, with quicker response to each action.
