    Psychometabolism [Acid]
    Level: Psychic warrior 2
    Manifesting Time: 1 standard action
    Range: Personal
    Target: One held weapon; see text
    Duration: Instantaneous
    Saving Throw: None

    Your weapon is corrosive, and sizzling moisture visibly oozes from it.

    with your successful melee attack. Your weapon is charged with acid until
    you make a successful attack.

    Augment: For every 2 additional power points you spend, this power<65>s damage
             increases by 1d6 points.
