Sword of the Sun

Weapon (any sword), legendary (requires attunement)

You have a +3 bonus to attack rolls and damage rolls made with this magic weapon. The weapon is made of pure sunlight, and deals radiant damage on hit.

When drawn, the sword radiates sunlight. It sheds bright light in a 30-foot radius and dim light for an additional 30 feet. You can focus this sunlight and cast a sunburst spell. When you do so, the sword does not radiate sunlight until the next dawn.
