Cups 

Camaraderie - (Flush) Your mask gains a number of charges equal to the number of Cups in your party. As a reaction to an ally within 60 feet failing a saving throw, you may spend a charge to add your proficiency bonus to the roll, potentially making it a success. (Reminder: only one player may use a Flush power per triggering event.)

Additionally, at the beginning of a session, you can toast your allies. Speak words of camaraderie and give a special inspiration to each of your fellow Harlequins that can be used during the session. After rolling an attack roll or ability check, they can use this inspiration to roll a D20 and must use the new result. Each cup can inspire their allies in this way, potentially giving them multiple uses of this inspiration.

Coordination - (Of a Kind) For the duration of each session, you have a bonus to using all tools/kits equal to the number of different suits in your party, up to a maximum +4 bonus.
