    Psychometabolism
    Level: Psychic warrior 4
    Manifesting Time: 1 swift action
    Range: Personal
    Target: You
    Duration: 1 min./level or until discharged
    Saving Throw: None and Fortitude negates; see text
    Power Points: 7
    Metapsionics: Extend, Empower, Maximize, Twin

    If you have a claw attack (either from an actual natural weapon or from an
    effect such as claws of the beast), you can use this power to produce a
    horrible poison that coats one of your claws. On your next successful melee
    attack with the claw during the power<65>s duration, the poison deals 1d8
    points of Constitution damage immediately and another 1d8 points of
    Constitution damage 1 minute later. The target of your attack can negate
    each instance of damage with a Fortitude save.
