Reflex Ring

A reflex ring allows the wearer to take an additional bonus action or reaction (but not both) during a round of combat. An ability or spell or event must still give the wearer the opportunity for either, as usual. The ring allows the wearer to take advantage of multiple opportunities in a round.

For example, a wearer of a reflex ring could make attacks of opportunity against multiple opponents who move away from him in melee. A rogue wearing the ring could use the Cunning Action feature as a bonus action, and also cast an available spell with a casting time of 1 bonus action. 

The ring has a maximum of 4 charges, and each use costs 1 charge. You may only use 1 charge per round. 1d4 of those charges are restored after a long rest.
