This category only lists Corrupted Creatures that are immune to Corruption and vulnerable to Purification. They naturally occur on the Corruption layer deep underground, but can also spawn on any type of solid corrupted block in darkness, no matter where. All Corrupted Creatures are aggressive (except on gameworlds with the "Pro" world option "peaceful creatures" enabled), strong and tough. They spawn during day and night and are not vulnerable to sunlight.
