As an action, a flash of light streaks toward a creature within 36 meters. Make a ranged spell attack against the target.
On a hit, the target takes 4d8 radiant damage, and the next attack roll made against this target before the end of your next turn has advantage, thanks to the mystical dim light glittering on the target until then.
If you miss by 4 or less, the target takes half as much damage, but no additional effects apply.
You can increase the damage by 6d8 for each additional mana or psi expended.
