CursedBlocks

A Spigot plugin for Minecraft 1.21.4. Every two minutes, a block type gets cursed. Touch it and you die.

The plugin scans the blocks around every online player and picks one at random — a single diamond ore has the same shot as a thousand stone blocks. Five seconds before the switch, a title screen and chat message warn everyone what's coming.

The sidebar tracks the current cursed block and the incoming one once it's decided. The actionbar counts down normally, then flips to a proximity alert if you're standing near a cursed block. Creative and spectator players are immune and left out of the scan.
