Gloves of the Paired Weapons

Wondrous item, very rare (requires attunement)

These sleek fingerless gloves seem to glow with power when the wearer holds two weapons, causing both weapons to faintly glow with the same energy.

When wielding two weapons, as long as one of them is magical, the other becomes a copy of the first, taking on all of its features and abilities and losing any that it had itself.
