Ice Clasper

The Ice Clasper is an uncommon Hardmode enemy that spawns in the Snow and Ice biomes. Ice Claspers attempt to ram and shoot frost bolts at the player. Though they normally collide with tiles, they are able to become intangible and travel quickly through tiles in order to reach the player. On contact it will inflict Frostburn and sometimes Glacial State, leaving the player open to be attacked by it again or by anything else in the area.

It can be detected with the Lifeform Analyzer.

Trivia

 * It appears to be an ice version of the Corruptor in both appearance and attacks, though Ice Claspers are faster and have the ability to travel through tiles.
