As dissolving touch, except your weapon is charged with acid until you make a successful attack.
Your touch, claw, or bite is corrosive, and sizzling moisture visibly oozes from your natural weapon or hand. You deal 4d6 points of acid damage to any creature or object you touch with your successful melee touch attack. Acid you secrete denatures 1 round after use, losing all efficacy and ability to deal damage. You are immune to your own acid.
