Chrysoberyl Ring

Chrysoberyl "Cat's Eye" ring
All nine of these rings were made by Rexfelis and were originally bestowed as gifts. All allow telescopic vision and vision in the dark. For those who are attuned to them, they convey nine life savings (when the wearer receives his or her death blow, they appear in the Catlord's manse fully recovered), It also slows the aging process greatly, perhaps even halting it entirely, like an enhanced Phylactery of Youth.  
Other powers include detect enemy (1/day), detect traps (1/day), detect magic (1/day), the ability to land on one's feet, climbing like a cat, and the ability to take the form of a black panther.
