Rain of Vitriol

Spell — see Magic and Spellcasting for the rules and the Spell Index for the full list.

Arcane 2 Type: blast, elemental (water)

Range: 180’ Duration: 1 round

This spell can only be cast outdoors in Drizzly or Rainy conditions. When the spell is cast, the caster designates a target point and all rain within a 10’ radius of the target point is transformed into vitriol (sulfuric acid). Each creature that begin its initiative in, or enters, the rain of vitriol must make a Blast saving throw.

If the save fails, the creature is soaked with vitriol. It suffers 3d4 extraordinary acidic damage immediately, another 2d4 extraordinary acidic damage at the start of its next initiative, and another 1d4 extraordinary acidic damage at the start of its subsequent initiative. If the save succeeds, the creature is merely splashed with vitriol. It suffers 2d4 extraordinary acidic damage immediately and another 1d4 extraordinary acidic damage on the start of its next initiative. If a creature takes an action in lieu of attacking to clean off the vitriol, it can reduce the amount of damage it or any ally suffers on subsequent rounds by 1 die. If a creature completely immerses itself in water (mere rain is not sufficient), it can reduce the damage it suffers on subsequent rounds to 0.

Metal and stone objects suffer minor corrosion from rain of vitriol, but the effect is merely cosmetic. Constructs or creatures made of metal and stone cannot be affected by the spell.
