Chilled

Chilled is a debuff inflicted by monsters native to the Snow biome and in Expert worlds when being at least partially submerged in water while you are in the Snow or underground Snow biomes (Leaving the water Will give you the debuff for 5 seconds). You can prevent this with the Arctic Diving Gear accesory. Like the Slow debuff, it slows your speed, although not as severely. While one can equip the Fast Clock to grain immunity to the Slow debuff, it does not prevent the Chilled debuff, which can only be prevented with the Hand Warmer accessory.

Most enemies that can inflict Chilled (the exception being Ice Elementals) can also inflict the Frozen debuff.
