So, first of all, a couple of restrictions I gave myself when composing this list:
- No flashy powers like pyrokinesis, especially not ones where you throw flames and fart around on firebursts like a rocket. This includes no powers that allow flight or some such as well as all kinds of magic missiles.
- Must adhere to at least some basic science and not be just miraculous 'magic', so no teleporting and no creating something from nothing.
- At the same time, the power should be one that can be used to emulate gothic and lovecraftian witches and other supernatural creatures to some extent. Controlling animals and weather and even time.
- The powers themselves should be broad and easily combined. Most psychic rules disappoint me in that they are mostly lists of effects rather than powerful tools and that you can hardly ever combine the effects of two different powers in a meaningful way. Psychic powers are not spells.
