Casts a cloud of acid, causing enemy equipment to rapidly lose durability and eventually break. Unlike the acid pools encountered in certain environments and enemies, this pyromancy reduces the durability of all equipment worn. Although it clearly has limited (if any) application when used against monsters, it is a potentially useful pyromancy in player to player combat.
Like all other spells, the amount of casts per slot increases upon reaching certain Attunement milestones:
|Attunement Level||Amount of Casts|
| Acid Surge • Chaos Storm • Combustion • Dance of Fire • Fire Orb • Fire Tempest • Fire Whip • Fireball|
Fire Snake • Firestorm • Flame Swathe • Flame Weapon • Flash Sweat • Forbidden Sun • Great Chaos Fireball
Great Combustion • Great Fireball • Immolation • Iron Flesh • Lingering Flame • Outcry • Poison Mist • Toxic Mist • Warmth
