Potentikinesis

Potentikinesis is power over magic in general. Susceptor specializing in potentikinesis can steal and manipulate the magical abilities of others, and create capsules to store said power, which can then be used by others. The creation and use of runes is an applied form of potentikinesis. Susceptor with natural affinities in potentikinesis have dark black skin. But not all, though. There have been stories around that light skinned people have this ability. Of course, like all other kinesises, it can be aquired as a skill, although no one is exactly sure how exactly to do it.
