As two actions, a bolt of lightning flashes down in a location you specify. Each creature in a cylinder centered on a point within 20 meters must make a Reflex saving throw.
On a failed save, a creature takes 5d6 lightning damage and is blinded and deafened until the end of its next turn.
On a successful save, it takes half as much damage and isn’t blinded or deafened by this spell.
You can increase the damage by 2d6 for each additional mana or psi expended.
