Scepter Quarterstaff

By speaking this weapon's command word as a bonus action, you activate a harsh purple light. While this light shines, you have advantage on Charisma (Intimidate) checks made to interact with beasts, dragons, fey, giants, humanoids, and monstrosities. In addition, any foe or object you strike with a scepter weapon glows, shedding dim light in a 10\-foot radius. Any attack roll against an affected creature or object has advantage if the attacker can see it, and the affected creature or object can't benefit from being invisible.

Versatile: This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.
