Aetherium Knuckles

Welcome to Prithalamuel's Wonders and Antiquities, have you been looking to add a little punch to your, well uh.. punch? Look no further, with the Aetherium Knuckles you'll gain an extra +2 to all unarmed attacks. Better yet you gain some unique abilities as well.

We're not quite sure why but these things have quite the magnetic field that can be manipulated to your advantage. Upon hitting a target, as a bonus action, an object within 90 ft with ferromagnetic properties that isn't bolted down or weighs more than 5 pounds will be drawn to them at an alarming speed. The target must make a Dex save throw (DC = 8 + Proficiency + Wisdom) or take 3d8 bludgeoning damage. This uses 2 charge(s).

Another fantastical property of this magnetic field is its tendency to create quite the shock. When rubbing your hands together, as a bonus action, you can create a static charge that deals an extra 1d8 lightning damage to your attack preventing the target from being able to use their reaction. This can then arc up to 3 other creatures if each one is within 10ft. Those being damaged from the arc take 1d4 lightning damage. This uses 1 charge(s).

Disclaimer: Upon using the catapult like abilities of the knuckles for the next hour any small (less than a pound) ferromagnetic objects within 5 ft of you will stick to your hands...

Notes: Bonus: Unarmed Attacks, Monk, Damage, Combat
