It's easy to create examples where Unified Power would seem to be appropriate, but applying Adjustment Powers with certain SFX creates illogical results. For example, take a telekinetic whose Blast, Flight, and Resistant Protection (force field) are all derived from his telekinesis. Unified Power would seem to make sense, since they are all manifestations of the same ability. Drain Telekinesis would reasonably affect all of them. OTOH, a Gravity Trap (Drain Flight) is defined narrowly as affecting one way that power is used. and should have no effect on others.
