A nimbus of shadows surrounds your hands, giving them the appearance of monstrous black claws. You may make melee touch attacks to channel the chill power of shadow into a target. If the attack is successful, the target must make a Fortitude saving throw or suffer 1d4 points of temporary Strength damage. A creature reduced to 0 Strength by this effect is paralyzed. At the end of this spell's duration, you suffer 1 point of temporary Strength damage. All Strength damage inflicted by this spell is recovered at the rate of 1 point per day.
