So im farming gb12 a lot right and i have some set rules like swift blue they need to have speed sub + another useful stat like hp% and they have to roll twice into swift or like fatal runes have to have attack/cd/cr in fourth slot and blue ones need to have two good fatal subs etc.. and similar for crit rate.
But i have no idea how to evaluate despair runes. which ones should i sell/keep/roll to see the stats i get?
