This ring sprang into being on the weirding workbench at Eldritch Hall: it took far less time than I expected, which was gratifying, but I now am ever so slightly suspicious of its eagerness to be out in the world.
Regardless, and despite any possible ill intentions on the part of this ring*, I have added it to the shop for immediate shipment to your cottage, castle, lair or apartment.
* I am reasonably certain its intentions are benign, but there are no guarantees in life. Wear at your own risk — but send us pictures if things get awesome.
