As an action, you can create a blinding light. Choose one creature that you can touch or see within 18 meters to make a Fortitude saving throw.
On a failed save, a creature takes 2d10 radiant damage and is blinded for the duration.
On a successful save, the creature takes half as much damage and isn’t blinded.
A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
You can increase the damage by 4d10 for each additional mana or psi expended.
