Bonus Damage Outside of Turn

BB-8 calls a resistance ally to assist him when he attacks out of turn. Running a team based on assists and out of turn attacks won’t be very good though. Right now, it looks like Bastila and Jolee will work best with Jedi and you can call Ezra for the assist.

Aaylaa counterattacks too. And she's a jedi.

OP wants to know the ones with higher out-of-turn damage, not the ones doing out-of-turn damage.

Aayla, Fives have additional counter damage. Ima-Gun Di's Leader Ability grants the thing on Jedi allies.
