About this Mod

FastCrystal

FastCrystal is a Fabric mod that optimizes and speeds up End Crystals for Crystal PvP.

Features

< 2.1.0

FastCrystal removes all interact and attack cooldowns, makes the client no longer rely on the server to send the crystal removal packet, and duplicates attack and interact packets for crystals.

This results in:

  • Faster crystal placement
  • Instant crystal breaking

>= 2.1.0

FastCrystal removes all interact and attack cooldowns for crystals and handles crystals entirely on the client.

This results in:

  • Instant crystal placement
  • Instant crystal breaking (2.1.3+)
  • Instant explosion sounds and particles, making it feel like you have no ping while using crystals

Server Opt-Out

Servers can disable FastCrystal for all players using the "fastcrystal:disable_fast_crystal" channel.

Using FastCrystal on Fabric servers also disables it for all players.

Frequently Asked Questions

FastCrystal server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.3). You can switch loaders with one click in the panel.

Is FastCrystal compatible with fabric?

FastCrystal officially supports fabric for Minecraft 26.3, 26.2, 26.1.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with FastCrystal – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if FastCrystal consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
