Zero Delay Crystals

Crystals Optimized is a lightweight Fabric client-side mod for Minecraft 1.21.1 focused only on end crystal responsiveness. It removes the normal client-side delay when placing end crystals and when attacking existing end crystals, making crystal interactions feel faster and more immediate.

This mod does not add automation, visuals, menus, or unrelated combat modules. It is intentionally simple: install it, launch with Fabric, and end crystal placement and crystal breaking will use zero client-side delay.

Because Crystals Optimized is client-side, servers can still limit, reject, or correct actions based on their own rules, latency, anti-cheat, and tick timing. Use it in single-player, private testing, or servers where this type of client-side timing change is allowed.
