Ice Golem

The Ice Golem is a hardmode enemy that is found in the Snow Biome, during the Blizzard and Blood Moon 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.

As they aren't too rare during the Blizzard event, it is possible to farm several Ice Feather and Frost Armor sets in some minutes.
