Requirements Your waking world is active.

Dust and pollen fill your waking world, obscuring creatures from sight. All creatures within your waking world become Concealed, and all creatures outside the area become concealed to creatures within it until the start of your next turn. In addition, a creature that ends its turn in the area must attempt a Fortitude saving throw against your world rouser DC as it inhales the particles. On a failure, it is Dazzled until the end of its next turn or Blinded on a critical failure.
