Embrace of Light

You weave your fingers through the air reciting ancient incantations, tearing reality open around you. You create glowing sigils on your clothing/armor, that shine brightly in a 20-foot radius, and shed dim light 20 feet after that. Creatures making a melee attack against you have disadvantage to hit you. Additionally, you can use your reaction to make a ranged spell attack against someone who has made an attack against you. You point and fire a beam of light at a target, which deals 2d8 radiant damage on a hit.
