At a glance
Install in the game only; not needed on the server
Crystal Optimizer
A client-side End Crystal optimizer for crystal PvP. When you place or break a crystal, the mod renders it on your client right away instead of waiting for the server to confirm. That hides most of the delay you'd normally feel from ping, so fights stay snappy even on a bad connection.
It all runs locally as a prediction. The server still decides what actually lands, but on your screen the crystal pops in and breaks the instant you click. Combos are easier to time when you're not fighting your own latency.
Features
- Instant client-side crystal placement
- Instant client-side crystal breaking
- Full configuration through Mod Menu
- Doesn't touch server-side behavior
Configuration
Open Mod Menu to toggle the optimizer and tweak the settings for your setup. You don't need any extra files or commands.
