Smoke (Su)

In battle, a nightmare exhales smoke that chokes and blinds foes, filling a 15-foot cone each round as a free action. Anyone in the cone must succeed on a DC 16 Fortitude save or become sickened until 1d6 minutes after leaving the area. This smoke acts as obscuring mist for the purposes of concealment. The smoke persists for 1 round. The save DC is Constitution-based.
