This is my Ares Kane gunslinger with +15 bow and skull of might, helm of might, armor of wizardy (to be a bit more tanky), wings of trinity. According to Razhk's guide to Capitol legendary, I need at least 7.2k+ damage to kill the boss but my Kane is only 6500. Even with rune all max, it will only be 6800 (I'm using one skill rune of resilience so I can't get 20% extra atk).
Similarly, I also have a lv 34 gs Cybella with only 4600 damage.
Anyway, is there like hidden way to increase the damage of my hero? I feel like I've done all that I can now(maybe giving up the resilience buff but that is currently way too OP right now so I can't)
Alternatively, this question is for people who've clear Capitol 3, how much damage do you have on your damage dealer? How much damage do you deal (after decreasing the boss defense and all)?
