Magic Eminence

Arcane Energy exerts an effect on the physical environment. Places with intersecting ley lines often can be identified by levitating stones.
Magical energy, when drawn into the body, causes grass to bow and creates ripples in water and sand. Exceptionally powerful mages have so much power that it causes water to form pinnacles in their presence. They may also be accompanied by a barely audible rumble and a sense of impending dread.
