Grimlore's Grimoire
0-level (Cantrip) Evocation
You may use your reaction to cause your physical form to emit a bright flash of light. This flash will shed bright light in a 10-foot radius and dim light for an additional 10 feet, centered on yourself. Additionally, if you are currently being grappled by a creature, it must succeed on a Dexterity saving throw or take 2d6 radiant damage and drop its grapple.
