As an action, you hold your hands outstretched as sand shoots forth. Each creature in a cone or line must make a Reflex saving throw.
On a failed save, a creature takes 1d4 slashing damage and is blinded until the end of its next turn.
On a successful save, it takes half as much damage and isn’t blinded by this spell.
You can increase the damage by 1d4 for each additional mana or psi expended.
