Balance

This weapon is of a dual nature and aligns itself with those who seek to find balance in mind and soul. Crafted from a mace of an assassin of Shar and a cleric of Selune, this mace is a testament to the nature of balance. Though it cannot be wielded in the natural sense, it can be released from a cursed ring wielded by the user.

You can use a bonus action to switch from the Blessing of Selune form, or the Wrath of Shar form.

Blessing of Selune: While in this form, the mace glows with silvery, radiant energy. While in hand, any time you restore hit points to a creature, it gains 1d10 temporary hit points. If its current hit points are less than half its maximum hit points, it gains 10 temporary hit points instead. As a bonus action, add one successful death save to an unconscious creature within 60 feet.

Wrath of Shar:  While in this form, the mace is shrouded in shadow and darkness, craving the souls of those it strikes. You gain a +2 bonus to attack and damage rolls with this magic weapon while in this form. The weapon has 3 charges. When you hit with an attack using Wrath of Shar, you can spend a charge to deal 2d6 additional necrotic damage. You regain hit points equal to half of the 2d6 result. Balance also loses 1 charge at dawn. During a short or long rest, a creature may restore 1 charge to Balance by expending 1 Hit Die without regaining any hit points.

Proficiency with a Mace allows you to add your proficiency bonus to the attack roll for any attack you make with it.
