Transmute Blood To Acid

Transmutation [acid, pain]
Level: Sorcerer */Wizard * 9
Components: V, S, M (a wax doll and a vial of acid worth 10 gp)
Casting Time: 1 Standard Action
Range: close (25 ft. + 5 ft./2 levels)
Target: one living creature
Duration: concentration (maximum 1 round/5 levels)
Saving Throw: Fortitude half
Spell Resistance: yes
  You transmute blood in the target's body to acid, dealing 1d6 points of acid damage/2 levels (maximum 12d6) each round.
  The creature is Staggered and Sickened by the debilitating pain. A successful Fortitude Save each round halves the damage and negates the Staggered condition for 1 round. If this damage reduces the creature to 0 or fewer hit points, it dissolves, leaving only the barest trace of remains. A dissolved creature's equipment is unaffected.
  Anyone who strikes the target with a non-reach melee weapon, Natural Weapon, or Unarmed Attack takes 3d6 points of acid damage as the acidic blood sprays on the attacker. If the attack is from a piercing or slashing Manufactured Weapon, the weapon also takes this damage.
  This spell has no effect on creatures immune to critical hits or bleed effects.
