    Dissolving Touch

    Psychometabolism [Acid]
    Level: Psychic warrior 2
    Manifesting Time: 1 standard action
    Range: Touch
    Target: Creature or object touched
    Duration: Instantaneous
    Saving Throw: None
    Power Resistance: No
    Power Points: 3
    Metapsionics: Chain, Empower, Maximize, Twin

    Your touch, claw, or bite is corrosive, and sizzling moisture visibly oozes
    from your natural weapon or hand. You deal 4d6 points of acid damage to any
    creature or object you touch with your successful melee touch attack.

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