Riptide Knuckledusters

Antique Knuckle Duster by retrovertigovintage

These old iron knuckledusters are found washed up on a beach, rusted and covered with coral. At a first glance they seem like something washed up from an old shipwreck but you decide that after a little cleaning up they could be of value to you.

That very same night, as you are on guard duty you pull them out and try to scrub off some of the coral. You scrub and scrub and notice the coral will not under any force be removed so you decide to give in and put them on. As you do so, your fingers seem to vanish into thin air. You can still feel them though, and they feel as if they have been submerged into freezing cold water.

The next morning you have your wizard friend take a look, he immediately recognizes portal magic. The finger holes  of the brass knuckles are small portals transporting your finger someplace that seems underwater. Maybe the shipwreck the knuckles came from? The hull of a great ship under the ocean!

But the water doesn't come through, it might be a one way portal? Or is it water at all?

You decide to give the magic knuckledusters a try and you notice that every now and a again you feel large scales rubbing on your fingers. When it happens you pull your hands out immediately. You've considered getting rid of them, or selling them but they turn bloodied enemies into a puddle of water when you hit them with a critical hit.
