Light Bringer

Prerequisite: the ability to case the light cantrip.

Your frequent use of your inner light has given you mastery over it. Once per turn, when you make an attack you may also cast the light cantrip as part of the attack, choosing either to have your weapon or a projectile you are firing, shed the light, or you may cast the spell on the target of your attack, requiring them to make a Dexterity saving throw as normal.
