Dawnbringer

Weapon (Longsword). Finesse, Versatile (1d10). Legendary [requires attunement by a creature of non-evil alignment]

Lost for ages in the Underdark, Dawnbringer appears to be a gilded longsword hilt. While grasping the hilt, you can use a bonus action to make a blade of pure radiance spring from the hilt, or cause the blade to disappear. If you are proficient with shortswords or longswords, you are proficient with the Dawnbringer.

The sword's luminous blade emits bright light in a 15-foot radius and dim light for an additional 15 feet. The light is sunlight. While the blade persists, you can use an action to expand or reduce its radius of bright and dim light by 5 feet each, to a maximum of 30 feet each or a minimum of 10 feet each.

You gain a +2 bonus to attack and damage rolls made with this weapon, which deals radiant damage instead of slashing damage. When you hit an undead with it, that target takes an extra 1d8 radiant damage.

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.
