History of Parasite

Parasite is a Solar Exotic Grenade Launcher from Destiny 2: The Witch Queen.

Overview

Its intrinsic perk, "Worm's Hunger", fires Hive worms that explode on impact. Explosion size and damage scale with the number of enemies defeated just before firing, which makes it strong against bosses.
