|lvl7=Your uncanny ability to shrug off damage improves as you are able to tap into the secrets of Undeath. If your Undead Fortitude is triggered by either a spell or a melee attack, your mastery over undeath instead absorbs some of the magic and damage. If you beat your Fortitude save by 5 or more, you absorb 50% of the damage inflicted rounded down as hit points. If you succeed, your attacker must make a Will save equal to 15 + 1/2 character level + Charisma Modifier or have the attack or spell reflected back to him, taking 50% of the damage rounded up. This effect does not work if the attack or spell is holy, good, radiant, or uses positive energy. If you succeed by 10 or more, you instead also regain one use of Undead Fortitude.
