I think this actually is with the Deathtrap Trigger evo selected - it's currently bugged to display the extra crit modifiers in the arsenal despite being a conditional proc.
Yep, idk if its actually a bug, or meant to show you the stats it would have when it would be active, since they will be always displayed as green next to the "actual" crit values. Thats probably not intended, since green just means "hey this stat was changed since you last looked", but hey... its a feature i guess lmao.
And ye, outburst or just cascadia accuracy for 300% cc on roll for 4sec. However, both have such diminishing returns from the crit this build already has, that just the +30% headshot multiplier from deadhead, outdamages further crit buffs by a lot. Also just having 0 recoil with that is nice, with the incarnon perk, tho ye you could also get that with stabilizer... but i cant fit that on anymore rn. :'D
