Your characters type will dictate much about their powers and evolution. The base categories have effects as follows.
Space/Time: These types have abilities that can innately effect the physical space and the fabric of time around them, allowing for such things as portal making and temporary time stop. While one of the most powerful surface types, these abilities are often double edged swords, making the user powerful, but also causing them health problems that go along with ripping your temporal body into particles and halting their flow through time, or working with space ripping power that gives off massive radiation levels.
Structure: These types have abilities that allow the generation of structures, be they complex mazes, or a very large hammer. Their abilities of often large and impressive, causing mass amounts of damage at their higher levels, but the use of their power tends to quickly fatigue their users.
Energy: These types are able to manipulate dampen or amplify energy, usually channeling them into blasts or latticeworks. The bare power of these types may not be immediately obvious, but with their lesser immediate effects, comes the potential for absolutely devastating high level attacks, and nearly impenetrable defenses. This being said, those starting out with energy manipulation will find themselves outclassed in most senses initially.
Psychoactive: These types are able to manipulate chemichal structure, generally in the brain, though it also lends itself to chemistry. They are able to alter the enemies mind state to show them horrible illusions, or boost an ally’s stamina at a crucial moment. At the highest levels complete manipulation of memory is possible, but utterly forbidden in most civilization quarters. The main disadvantage of this type is its susceptibility to being physically overtaken. While it is great to have the ability to plunge everyone around you into mental breakdown, it doesn’t help if you are stabbed.
Pure Sound: These types utilize the pure potential of sound and vibration to (at high levels sometimes litteraly) rock the opponents world. Huge blasts of sound, hypnotic songs, and other tricks of thetrade are all in the repitoir of this type, however, the constant exposure to their own power often begins to destroy the mental state of their users if overdone.
