Halberd of Throne's Command

This weapon is bedecked in ornate gold filigree and deep-blue and maroon jewels. You gain a +1 bonus to attack and damage rolls made with this weapon. Additionally, you gain proficiency in the Intimidation and Persuasion skills if you don't already have it.

Spellcasting: The weapon has 5 charges. You can use a bonus action and expend 1 or more of its charges to cast one of the following spells (save DC 16): Command (1 charge), Zone of Truth (2 charges), Compulsion (4 charges), Banishment (4 charges), or Dominate Person (5 charges). The weapon regains 1d4 expended charges daily at dawn.

Heavy: Creatures that are Small or Tiny have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small or Tiny creature to use effectively.

Reach: This weapon adds 5 feet to your reach when you attack with it, as well as when determining your reach for opportunity attacks with it.

Two-Handed: This weapon requires two hands when you attack with it.
