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 spell deals 2d4 points of acid damage with no splash damage.

Augment: For every two additional spell points you spend, the acid, unless somehow neutralized, lasts for another round. The acid then deals another 2d4 points of damage in that round, on your turn.
