Phantom Blade Bracers

Wondrous item, rare (requires attunement)

Protective gear worn by the changeling diplomat Atrus, these steel bracers are each inlaid with a single sapphire on their interior. At the end of each bracer is a small protrusion in the shape of a sword’s hilt, which can be looped through the wearer’s sleeves to act as cufflinks.

While wearing the bracers, you gain a +1 bonus to AC if you are not wearing medium or heavy armor.

You can use an action and speak the bracers’ command word to cast the eldritch blast cantrip from them. The cantrip conjures magical blades that deal slashing damage instead of beams that deal force damage, and you can make either melee or ranged spell attacks with the conjured blades.

Each bracer is connected to an extradimensional space that can be used to store a single weapon. Each bracer can hold up to 20 pounds, not exceeding a volume of 16 cubic feet. The bracers weigh 1 pound, regardless of their contents.

You can use an action store a weapon inside of one of the bracers by holding it close to the bracer’s sapphire, transporting it into the bracer’s extradimensional space. Retrieving a stored weapon from a bracer requires you to use a bonus action. When you reach into the bracer to retrieve the weapon, the weapon magically appears in your hand.

In addition, a weapon stored within one of the bracers becomes magically bound to it. If it is on the same plane of existence, you can summon that weapon as a bonus action on your turn, causing it to teleport instantly to the hand wearing the associated bracer. A weapon remains bonded with one of the bracers until a different weapon is stored in that bracer.

Placing either of the bracers inside an extradimensional space created by a bag of holding, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane.

The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it and deposited in a random location on the Astral Plane. The gate then closes.

The gate is one-way only and can’t be reopened.
