Small sandstorm

The caster concentrates and stirs up dust, earth or sand within their line of sight. A small sandstorm 2 paces high and 2 paces wide forms for 1d4 rounds.

Anyone in the centre of the sandstorm must make a Perception check, with at least as many successes as the spell's power. Otherwise, they are blind for the duration of the spell, with all penalties to blindness.
