Fastest possible crystal optimizer
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.

FastCrystal server crashes on startup – what to do?

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. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
