*Acid, Very Rare*
****
A creature that is subjected to this acid must make a DC 15 Dexterity saving throw. On a failed save, the creature takes 6d12 acid damage and is subjected to the effects of the acid. On a successful save, the creature takes half damage and doesn't suffer its effects.
When a creature suffers the effects of this acid they are covered in it, causing them to take 2d4 acid damage at the start of their turn. As an action, they or an ally can scrape off the acid to stop this effect. While covered, the creature is in a delirious state, not knowing any harm that that comes their way. At the start of their turn, the creature must make a DC 15 Wisdom saving throw to end this state. While delirious, the creature does not feel any harm done unto it, and cannot perceive any hostility causing all attacks it makes to be done with disadvantage.
