Absorb the Mind
The Kiasyd absorbs the Abilities from her victim's mind, and she is able to call on them immediately, even though she might have never has knowledge of them before. This power is invasive, actually stealing the Abilities permanently, leaving their original owners ignorant and inept.
System: The player rolls Perception + Empathy (difficulty of the target's Willpower). The target may resist with a Willpower roll (difficulty of the Kiasyd's Willpower). The difference between the two determines the effect. If the target gets more successes, he resists completely. The Kiasyd, if successful, may select a combination of Abilities to her satisfaction. Taking some of a victim's Ability dots may leave a remaining bit -- the Kiasyd need not take all of a subject's dots in a given Ability. (For example, a character with three dots in Occult, from who a Kiasyd steals one, retains an Occult of 2.)
No subsequent attempt ca be made by the Kiasyd on a target against whom he fails the Perception + Occult roll for at least a year. In all cases, the maximum to which the Kiasyd can raise an Ability is the level the target has in that Ability. (Again by example, if a victim has a dot in Law and the Kiasyd gets 2 successes, she can't gain 2 dots in Law.) Also, generation restrictions apply; a Sixth Generation Kiasyd can have a maximum of seven dots in an Ability. All losses of Abilities on the part of the victim are permanent, though they may be returned to their original levels via experience-point expenditure.
