You have a power that activates whenever you touch people, whether you want it to or not. Choose one power that can affect targets at range (either Touch or a range in feet) and that has a negative effect (damage, blindness, etc.). The power goes off whenever you make skin-to-skin contact through anything thinner than cotton or polyester cloth.
In combat, your clothing can be cut or ripped off, therefore whenever you occupy the same square with anyone who is not completely covered, make a Reflex save (DC 10) to avoid skin contact. Occupying the same square includes moving through spaces occupied by comrades. You can also accidentally set off your power by Aiding Another, getting or giving first aid, searching through someone’s possessions, exchanging objects, or anything else the GM deems to have a risk of skin-to-skin contact. The GM can also, as the situation dictates, either raise or lower the Reflex save DC.
If you fail your Reflex save, the power activates as normal (causing damage, provoking a saving throw). Both Touch attacks and ranged attacks alike are both presumed to be “hits” by virtue of failing the saving throw. You expend PPs as normal. If you do not have any PPs left, nothing happens. Don’t bother with the Reflex save.
You can take this Comp up to 4 times. Each time, it increases both your Reflex save (to avoid contact) and your Constitution save (to resist ability damage) by 5. Alternatively, if you take this Comp multiple times, you can apply it to a different power each time, in which case you can take it as many times as you have separate powers.
