Catches cheats trying to hide by adding random delays.

Automatic Crystal Detection

Tracks when players right-click obsidian or bedrock with an End Crystal and instantly break it.
Flags players who are consistently dropping below a 45ms window between placing a crystal and blowing it up over a sustained sample size.

Shield Stuns

Keeps track of how many times a player attempts an anchor/crystal explosion versus how many times they successfully land it, providing real-time accuracy data to admins.
