Corrosive Urns are offensive items in Dark Souls II.
- Urn filled with secretions from giant corrosive ants. Powerful acid inflicts damage on equipment.
- Giant anthills created by the corrosive ants line the horizon of the desert land of Jugo. Ant larvae are considered a delicacy, but he who enters an anthill will have his flesh melted to the bone.
A fast-moving thrown object that is similar to a firebomb, except instead of dealing damage to the enemy's health, it damages their equipment with corrosive acid.
Although most enemies are unaffected by its effect, Acid damage can prove invaluable in PvP.
