Your touch progressively transmutes the substance of creatures you touch into stone. Once per round, you may deliver a touch attack that inflicts one step of Dexterity damage and slows the target (as the spell) for 1 round. A successful Fortitude save negates the slow effect but not the ability damage. A target brought to the final step on the Dexterity damage track is petrified permanently (rather than being killed). Break enchantment, restoration, or stone to flesh can reverse the effects of calcific touch.
