Umbrakinesis

Umbrakinesis (also called Erebokinesis), or shadow manipulation, is a kind of kinetic magic that many Shadows are skilled at.

Umbrakinesis works as a form of conjuring. At its most basic level, the practitioner can project what appears to be independently moving shadows on walls (or similar). A skilled umbrakinetic can conjure tangible darkness, which appears as black smoke or clouds. Similar to folds, this can then be molded into physical objects, like weapons or a flock of bats. Umbrakinesis has a wide range of uses, from elaborate shadow puppets to usage in combat. It can bind people with seemingly intangible shadows, create "spheres" or "rays" of darkness, or even create "curtains" of darkness to block off areas with what seems to be an empty void. Tangible umbrakinetic conjurations are more powerful, but more difficult to produce and more easily destroyed than intangible conjurations.

Umbrakinesis works best in half-light, such as firelight, which provides just enough light to create deep shadows. Umbrakinesis is difficult to wield in full light, but impossible to wield in total darkness. Bright light will keep an umbrakinetic at bay, but the true way to defeat one is, ironically, to remove all sources of light. This will deprive an umbrakinetic of shadows, and they will be unable to form tangible objects.
