    Assimilate

    Psychometabolism
    Level: Psion/wilder 9
    Manifesting Time: 1 standard action
    Range: Touch
    Target: One living creature touched
    Duration: Instantaneous and 1 hour; see text
    Saving Throw: Fortitude half
    Power Resistance: Yes
    Power Points: 17
    Metapsionics: Empower, Maximize, Twin

    Your pointing finger turns black as obsidian. A creature touched by you is
    partially assimilated into your form and takes 20d6 points of damage. Any
    creature reduced to 0 or fewer hit points by this power is killed, entirely
    assimilated into your form, leaving behind only a trace of fine dust. An
    assimilated creature’s equipment is unaffected.

    A creature that is partially assimilated into your form (that is, a creature
    that has at least 1 hit point following your use of this power) grants you a
    number of temporary hit points equal to half the damage you dealt for 1
    hour.

    A creature that is completely assimilated grants you a number of temporary
    hit points equal to the damage you dealt and a +4 bonus to each of your
    ability scores for 1 hour. If the assimilated creature knows psionic powers,
    you gain knowledge of one of its powers for 1 hour.
