The sandspray spell causes a pillar of sand up to 30 feet high to erupt around one creature. The blinding spray causes 1d6 damage for every two levels of the caster (round down) and requires no attack roll. The creature is allowed a saving throw vs. spell for half damage. Even a creature that saves will be blinded by sand for 1d4+1 rounds. While blinded, the creature cannot cast spells and attacks with a -4 penalty.
The material component is a pinch of sand.
Notes: Common for spellcasters from an Arabian setting; otherwise, very rare.
