Arlen's Many Gauntlets

This steel gauntlet extends up to the elbow and appears finely polished, embossed with the shapes of miniature weapons at its wrist. This gauntlet was wielded by the mythic and long-dead warrior Arlen, who is remembered now only through legends of his incredible fighting prowess. The gauntlet contains ten extradimensional spaces, each of which are capable of containing a single weapon. When you discover the gauntlet, 1d6 weapons are already inside its extradimensional spaces. The DM chooses each weapon or determines it randomly on the Gauntlet Weapons table.

You can use a bonus action to summon a weapon from an extradimensional space or stow a weapon from your hand into an empty space. For each unique rarity of magic item stored within the gauntlet (uncommon, rare, very rare, and legendary), you gain a cumulative +1 bonus to attack and damage rolls made with all nonmagical weapons.

While wearing the gauntlet, you can use an action and speak a command word to summon a spectral companion gauntlet onto the arm of a willing creature you touch, remaining until dispelled. This spectral gauntlet allows the affected creature to summon and stow weapons inside the gauntlet as normal.

The gauntlet has 5 charges. While wearing it, you can expend 1 charge as an action to summon up to ten weapons from the gauntlet, each wielded by a spectral gauntlet that appears up to five feet away from you or a creature wearing a spectral companion gauntlet as described above. You can make a melee attack against a creature within range of each weapon using your modifiers. The gauntlet regains 1d4+1 charges daily at dawn.
