A jagged toothed metal clamp, with intricate runes and magical frameworks carved directly into it, is connected to a brass handcuff via length of golden chain. The apparatus gives of an ephemeral golden glow. A small plague along the handle of the clamp reads "Yakupo's Instant Attuner".

As an action a creature can fasten the handcuff around their wrist and attach the clamp to one magic item that requires attunement. If the creature fulfills the requirements to attune to that item they become instantly attuned to it. This attunement does not require an attunement slot and is considered a temporary additional attunement slot. The creature remains attuned to the item for 1 minute or until the creature dies. When the attunement ends the attuner detaches from the creature and the magic item and is destroyed, becoming an ordinary non magical object.
