New Debuff - Accuracy Down

I just came across this like right now, oddly enough it was on Savage Opress as well, I looked at the team I was running, and nobody had anything about accuracy down, Boba Fett, Fives, Mace Windu, Kylo (Masked), and Sion. I checked Savage Opress and his kit and nothing was added about giving himself accuracy down or anything like that.
