Note that none of the Ten Ring of Qwaar the Axiomatic function if the wearer is employing any other type of magic ring, but that all ten Rings of Qwaar will function together just fine.

A rumor among certain sages indicates that the possessor of all ten rings may access the Secret Ultimate Power of Qwaar, but that's probably just scholars conflating the rings with the Rod of Seven Parts.
