Shadow Form

[leonmallett]

Powers Unlimited One offers a lot of Shadow powers including APS: Shadow. As a GM I generally allow APs type powers to be made permanent as they often have a very big downside (like normal human interactions....). But if so they cannot be switched off except by exertion of a Negate type power.
