Re: Limited Power Campaign Premise
Wow, I’m actually working on an outline for a graphic novel based on a similar premise; all powers are TK/psychokinesis based, but with a very limited set of possible effects. Anyway, some power examples for your idea:
Pyrokinesis/Fire-starting: SFX is you increase the speed of molecular movement in an object, thus increasing its heat. Flammable objects will ignite fairly easily. Probably built as a low level RKA with Indirect and Heat/Fire SFX.
Temperature control: Heating or cooling a limited area (and any combat or PER modifiers you can justify for that effect) up to 3 spaces on the temperature scale. Again, you are dealing on the molecular level, increasing or decreasing speed to adjust temperature.
Invisibility: Bending light using TK. would probably have a fringe.
Tactile Telekinesis: Expanding on the TK based extra STR, you can build a whole suite of powers based on not being able to knowingly project your TK energy. This was the explanation for Superboy’s (the clone one, from after Big S died) powers. You can justify Speed, Strength, “invulnerability” (Force Field), Flight, and a whole lot more.
