Corpse Grub

Corpse Grubs are enemies in Dark Souls III.

Description
The evolved form of the parasites residing in Infested Corpses, these vile creatures are comprised entirely of maggots. Most of them appear in a waterway in the Cathedral grounds and one is found in a cell in Irithyll Dungeon that drops the Great Magic Weapon sorcery.

Strategy
Like the other maggots enemies, Corpse Grubs inflict the maggot status with their attacks which can be removed with a torch. Although stronger and more aggressive than their infected hosts, they share the same weakness to fire damage and will writhe in agony if set alight.
