Dawn Shard Scimitar 2014
Weapon, uncommon, (requires attunement)
The blade of this magic weapon gleams with a faint golden shine, and the pommel is etched with a sunburst. As a bonus action, you can command the weapon to shed dim light out to 5 feet, to shed bright light out to 20 feet and dim light for an additional 20 feet, or to douse the light. The weapon deals an extra 1d6 radiant damage to any creature it hits. This increases to 2d6 radiant damage if the target is undead or a creature of shadow.
Properties
Finesse
When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.
Light
A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
