    Share Pain, Forced

    Psychometabolism
    Level: Psion/wilder 3
    Manifesting Time: 1 standard action
    Range: Close (25 ft. + 5 ft./2 levels)
    Target: One creature
    Duration: 1 round/level
    Saving Throw: Fortitude negates
    Power Resistance: Yes
    Power Points: 5
    Metapsionics: Extend, Twin

    As share pain, except as noted here.

    You attempt to force the sharing of your wounds with an unwilling creature,
    and for less time. If you are immune to the type of damage dealt, the target
    takes no damage.

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


    Implementation notes:
    You may not have more than one Share Pain or Share Pain, Forced active at
    any one time. Any subsequent uses override the previous.
