MobChunkChallenge
Turn every Minecraft world into a challenge!
Whenever a player enters a new chunk, a random hostile mob spawns. The chunk becomes locked and players cannot leave it until the mob has been defeated.
A visible particle border marks the chunk boundaries so you always know where the challenge area ends.
