Mace of the Black Crown (Dormant)

Weapon

Legendary Requires Attunement

This mace has a haft of black iron and a ruby head with a fiendish countenance. Dormant. The mace grants the following benefits in its dormant state:

You gain a +1 bonus to attack and damage rolls made with this magic weapon.
While holding the mace, you can use a bonus action to speak its Infernal command word, causing flames to erupt from the head. These flames shed bright light in a 40-foot radius and dim light for an additional 40 feet. While the mace is ablaze, it deals an extra 1d6 fire damage to any target it hits. The flames last until you use a bonus action to speak the command word again or until you are no longer holding the mace.
While holding the mace, you can use an action to summon an imp. Any devil you summon with this mace is friendly to you and your companions for the duration. The imp obeys any verbal commands that you issue to it and returns to the Nine Hells 10 minutes after you summoned it. This property can't be used again until the next dawn.
