LavaRise | Rising Lava Challenge with UHC Supply Drops | 1.21.1

LavaRise
LavaRise is a lightweight Paper plugin that transforms your world into an intense survival challenge. Once the event begins, lava slowly rises from just above the bedrock layer, consuming everything in its path while valuable supply chests appear just above the lava, forcing players to take risks for powerful loot.

Designed for UHC events, SMPs, challenge servers, and content creators, LavaRise focuses on performance, simplicity, and exciting gameplay.
