Dawnbringer
Dawnbringer is the legendary sword of Duke Thesan. It burns its foes with the light of dawn and creates a radiant explosion around the wielder. Undead killed by the explosion disintegrate and leave behind an ash pile. Light emanates from Dawnbreaker's cross-guard, an effect that is particularly pronounced in nighttime hours or in areas without illumination.
This weapon grants a +3 bonus to attack rolls made with it and deals 2d8 additional radiant damage on a hit. Upon hitting, the sword also deals an extra 2d8 radiant damage to vampires or other creatures with sunlight sensitivity.
Burn at Dawn. While holding this sword, as an action you may cause a radiant explosion (15ft in radius) to eminate from the wielder. All enemies within the radius must make a constiution saving throw or take 5d10 damage and be knocked back 10 feet. On a successful save, creatures take half damage and are not knocked back. Undead and oozes have disadvantage on this saving throw.
Healing Rays.While holding the weapon, you can use an action to touch a creature with the blade and cast Lesser Restoration on that creature. Once used, this ability can't be used again until the next dawn.
