The Eternal Acid Exotic fusion rifle [i]Watch your step[/i] Exotic perk: Acid: every missed shot creates a small acid pool ( 1 foot in diameter, but each shot in the burst leaves one) that lasts 10 seconds. If an enemy steps in the acid they get DoT for 3 seconds (like thorn). If a guardian is killed by this fusion rifle, they will liquify into a 4x4 pool of acid that lasts 13 seconds
