By absorbing some incoming elemental damage, the archaic device could convert that energy into blasts of force. This energy additionally energized the wielder's other weapons, allowing them to deal extra force-based damage.
The archaic device was stored alongside an ancient gemstone at the Temple of Mystra at some point before the deity's death and the Spellplague of the Year of Blue Fire, 1385 DR. The temple quickly became abandoned.
In the Year of the Ageless One, 1479 DR, after Ana Brabener was rescued by adventurers from the slavers Eldrin Szind, Odezzt Avithoul and Phargred Avithoul, the archaic device was taken from the temple.
