A magical arrow of acid springs from your hand and speeds to its target.
You must succeed on a ranged touch attack to hit your target.
The arrow deals 2d4 points of acid damage with no splash damage.
For every three caster levels (to a maximum of 18th), the acid, unless somehow neutralized, lasts for another round, dealing another 2d4 points of damage in that round.
Material Component: Powdered rhubarb leaf and an adder's stomach.
