The Lich King subsists off the life force of others, maintaining a youthful energy while those around them wither and age.
When the Necromancer makes eye contact with a person, they are able to siphon off a large chunk of that person's life essence, causing rapid aging and slowing the Necromancer's own aging down. They are unable to retain youthful beauty, however, and appear skeletal and pallid.
Exert your Mind and make a Charisma + Occult roll, which the target can resist by rolling their Body. Target is aged by your Outcome in years if you succeed, and you cease to age for one tenth that amount. Cannot be used beyond a range of Arm's Reach, and you must make direct eye contact with them in order to activate the power. Every time you activate this power, you must make a Trauma roll.
If target is human and aged beyond 40 they must roll Brawn difficulty (age/10 rounded down). If they fail, they lose Attribute point from either Perception, Brawn, or Dexterity (chosen randomly). Botches subtract additional Attributes. In the event that they are aged more than 10 years, they must make one such roll for each decade. Reducing any Attribute to 0 causes death (A Perception of 0 causes an indefinite coma).
