Floaty Gross

The Floaty Gross is a floating Hardmode Enemy that spawns in the Underground Crimson. They can float through Blocks in a manner similar to Wraiths and can inflict the Weak debuff. They are immune to the Confused, Poisoned, Venom, On Fire!, Cursed Inferno, and Shadowflame Debuffs. Because of their low knockback resistance and ability to pass through walls, weapons with low knockback will be more effective against them in the narrow confines of the Underground Crimson.
