FreezeZone
About
A survival world-freezing plugin for Minecraft *.21. Features gradual biome conversion to icy biomes within a 5000x5000 block area, a shrinking safe zone mechanic triggered by /freeze start, and player freezing effects in the danger zone. Players caught in the danger zone for 30 seconds become immobilized; others must ignite them with fire charges to free them, giving 60 seconds to escape. Only affects surface areas, with snowflake particle effects at danger zone borders.
