Per the description:
If you die while wearing the ring, your soul enters it, unless it already houses a soul. You can remain in the ring or depart for the afterlife. As long as your soul is in the ring, you can telepathically communicate with any creature wearing it. A wearer can’t prevent this telepathic communication.
Our party has found a such a ring that already has a soul in it. And he is quite the chatterbox.
Only the wearer can hear, but the soul is known to talk late into the night, yell when the wearer is trying to concentrate, and tell bad jokes at the wrong time. And frankly, we're fed up with it.
Per the description, the soul can choose to leave, but is there a way to make it leave?
It the description of the Sword of Vengeance, it calls out:
You can break the curse in the usual ways. Alternatively, casting banishment on the sword forces the vengeful spirit to leave it. The sword then becomes a +1 weapon with no other properties.
But there is no such clause for the ring. Are we stuck with Murray forever?
