Most liches rarely use their touch attack, instead preferring to rely upon their powerful spells. Not so for you.
Benefits: Your touch attack deals 2d8 points of negative energy damage +1 point of damage per Hit Dice of the lich. If you use your touch attack to heal any undead (including yourself) damage heals at this improved rate.
