Ice Golem

The Ice Golem is a hardmode enemy that is found in the Snow Biome, during the Blizzard event. It possesses a damaging melee attack as well as a ranged laser which freezes players. They are immune to the Poisoned, Venom, Confused, and Frostburn debuffs. They can be found at both day and night. A good way to know one has spawned is a blue lazer beam somewhere in the air.
