Lightbringer

+1 Longsword, Uncommon.
When its wielder commands, Lightbringer
glows as bright as a torch.
While glowing, Lightbringer deals an extra
1d6 radiant damage to undead creatures.
Made in the Forge of Spells for a cleric of Lathander,
the god of dawn, the pommel of this longsword is
shaped like a sunburst and made of solid brass.
