This spell temporarily transforms the caster's arm into a retractable, rubbery appendage that she or he can extend up to 10 feet and use to strike at foes with at +1 bonus to normal attack rolls. The arm ends in a taloned claw that rakes foes for 1 d4 points of physical damage plus 1d4 points of unearthly magical cold damage (2d4 points total) on a successful attack. Undead creatures are unaffected by this chilling damage. Victims are allowed a saving throw vs. spell to take only half of the chilling damage.
While his or her arm is transformed, the priest is unable to work spells involving somatic components.
Notes: Granted by the evil god Cyric in the Forgotten Realms setting.
