Open world pve
Just farm the first map or the great tree on the third map (plus other events) till you unlock Chronomancer and then just spam Shatter and kill everything.
Sinister is fine for now.
Eyeballing Viper though, with the nerf to condition duration food the Expertise on Viper is interesting.
Thanks for the advice. I haven’t made sinister yet. Right now, i’m running full zerk, and I’m not sure if I should switch or not.
