Corrosive acids deal damage each round of exposure. The amount of damage varies depending on the acid’s strength, as noted on Table: Acid Damage.

Table: Acid Damage
Acid Strength Splash Attack* Total Immersion*
Mild 1d6 1d10
Potent 2d6 2d10
Concentrated 3d6 3d10
*Damage per round of exposure.

Acid damage from an attack reduces hit points. A character fully immersed in acid takes potentially more damage per round of exposure than a character splashed with acid.

The fumes from most acids are inhaled poisons. Those who come within 5 feet of a large body of acid must make a Fortitude save (DC 15) or take 1 point of temporary Constitution damage. A second save must succeed 1 minute later to avoid taking another 1d4 points of Constitution damage.
