Blood mist

You command Rävãryn the blood-hollow to rupture its reservoir, releasing a dense, chilling cloud of coagulated crimson vapor. The mist pours outward in a 30‑foot radius centered on you, heavily obscuring the area for all creatures except you. The air becomes thick, metallic, and unnervingly warm, pulsing faintly with stolen heartbeats.

While inside the mist, you can see normally. Hostile creatures treat the area as difficult terrain.
