This is the power to drain life energy from all semi-intelligent or intelligent beings, friend and foe alike, within a 10 meter radius of the mutant. This range is increased by 3 meters for every 4 points of mental strength possessed by the mutant. Life leech will drain away 6 hit points per melee turn (i.e., cause 6 points of damage) from each being in range and add a like number of hit points to the mutant's total. If the mutant with life leech takes damage, the hit points are first subtracted from those points leeched. Those leeched hit points that are not destroyed in combat dissipate after 24 hours.
