Well, if we do that then we might as well give "Minor Blood Manipulation" to anyone with a cardiovascular system. "This dude breathes, that counts for Air Manipulation." Then again,
Rayman has "Body Control & Telekinesis" on his profile, so maybe people here wouldn't object to copy-pasting that justification for Madness characters, preferably to only the Nevadean Physiology page.
By the way, you weren't kidding about the Magiturge being OP. The Toxic Orb affecting enemies on a "cellular" level, the Static Orbs on "ion[ic]" level, Thaumergy "tear[ing] the universal fabric upon which your enemies are written" (which with how The Machine comprises reality might be as extensive as Plot Manipulation or at least Info like on Dr. Crackpot's profile), however you want to classify the "Death" status inducement -- and all this being quite spammable and AoE! Plus still having access to Dissonance weapons.
