Ryuu Crystal Optimizer
by 4ZRyuu
Ryuu Crystal Optimizer is a client-side Fabric mod that changes how the game handles End Crystal placement and breaking for players in Crystal PvP.
What it does
The mod changes only how the local game processes End Crystal interactions. Placement and breaking animations play more smoothly and respond with less visual delay after each action on screen. Players who fight with crystals will notice faster, more fluid combat on their own screen.
Because the work happens on the client, the server needs nothing installed and joins a multiplayer game unchanged. The author describes the mod as lightweight and single-purpose, with minimal performance impact. It cannot lower the actual network ping, since server mechanics stay untouched. Files exist for Fabric across 12 release versions, 1.21 – 1.21.11, under the Apache License 2.0, and the mod is not open source.

Smoother crystal placement

Single-purpose design

No server-side changes
