Condition to crit
Well you really need to have 30 trait point in Critical Strikes before it become good. Then again, the same could be said for any trait tree.
I’m not sure what weapon set you were using before but Sword + Pistol is generally the best choice for leveling and offers many of the same benefits as Death Blossom spam (evades and multi-target damage). I’d recommend you give it a try.
The idea is quite simple. Maintain Black Powder while auto-attacking or simply spam Pistol Whip.
