Activate envision
Trigger You use a feat or ability to reroll a failed or critically failed Reflex saving throw (such as Cat's Luck or Halfling Luck).

This clay figurine resembles a white cat with a paw outstretched. When it's activated, any allies within 10 feet who also just failed or critically failed a Reflex saving throw from the same source (such as a fireball spell) can also reroll their saving throw and use the better result.
