by Shikaru
Shikaru's Crystal Optimizer changes how client-side packets for crystal PvP are handled, so crystals resolve with less delay on the player's side.
What it does
The mod reduces the client-side delay tied to crystal PvP by sending packets directly and placing crystals on obsidian or bedrock without a wait. It is a lightweight Fabric mod, and its code is open source under the MIT License. Only the client needs it, so servers run without any change.
