Weapon (longsword), Versatile, Legendary, Requires Attunement
This sword is an Elven Steel weapon, granting the benefits of an elven-crafted weapon. This weapon is also considered a +3 magical sword granting a +3 bonus to attack and damage rolls made with it.
While attuned to this weapon you gain advantage against all fear and charm effects.
Doom of Damocles: Activating this ability, you can levitate the Sword of Damocles over a creature's head. While the Sword of Damocles dangles over a creature's head, they have disadvantage on all fear effects. On a subsequent turn, as an action, you can make the target make a Wisdom Saving throw. On a fail, the target succumbs to the effects of the Frightened condition and the sword drops, dealing 6d8 slashing damage to the target. On a success, the target does not become Frightened and takes half damage. The sword then returns to the attuned's hands. If you have no free hand to catch the sword, it drops to the ground. You can use this ability a number of times equal to your proficiency bonus. Once these uses have been expended you must complete a long rest in order to use it again.
