Frost Golem

Frost Golem is a hard mode monster introduced in the 1.2 update. It has 3000 hit points, and shoots light blue lasers that apply the Chilled debuff, which slows movement speed. If you are hit again while chilled, you will be frozen in place for a few seconds, unable to do anything. They spawn in the snow biome, and are rather common during Blood Moons. They drop a piece of Frost Armor when killed.
