And another batch of ideas:
 * Seismics: User releases seismic energy onto their target. Can be used to create quasi-earthquakes or cause some form of structural damage within an inorganic object. Can be used to disorient enemies and knock them off balance. Main drawback would be that users would be just as vulnerable to their own tactics, meaning it can backfire on them.
 * Internal Compass: Users of this are a bit more acute to magnetic fields than the average Homo sapien. They can detect magnetic fields (and maybe poles too), but can't really manipulate them like Pyrrha does. All they have is better sense of direction. The compass can be disrupted or confused by changes in magnetic forces. Might be good for tracking or avoiding Grimm and other threats.
 * Imitation: Users can mimic the voice of a person or creature. They'll have to remember to act in character, though, when used against humans or Faunus. Grimm can still sense the emotions of users, and Faunus might be able to catch the user's scent.
 * Vacuum: Users can suck out the air around them, allowing them to make suctions, suffocate their victims, and/or releasing the trapped air into a concentrated blast of air. When vacuums are created, sound may not travel through them (without any molecules to vibrate). However, they might risk sucking out the air in their lungs as well, and may need to hold their breath. Not sure if they can suffocate Grimm, given the lack of knowledge regarding their biology (assuming that they're even biological entities).
