As two actions, you create two star-like motes in your space. They float in the air and orbit you for the duration. If you have four or more motes remaining, they shed bright light in a 5-meter radius and dim light for an additional 5 meters. If you have one to three motes remaining, they shed dim light in a 5-meter radius.

When you cast the spell—and once on on each of your turns thereafter as an action—you can expend a mote, sending it streaking toward a point within 20 meters. Once a mote reaches its destination or impacts against a solid surface, the mote explodes. Each creature within 1 meter of that point must make a Reflex saving throw.

On a failure, it takes 2d8 radiant damage and is blinded until the end of its next turn.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

Augment

You can increase the number of motes by 2, the damage by 1d8 for each additional mana expended, and the damage by 1d8 for every two additional mana expended.
