here are my drops from 136 runs level 8 GOL:
i'm farming more for immunity and like the the extra value from these souls but these talismans hardly ever drop. that's really bad for such crucial talismans, the droprates should be much better (and the % were increased a few updates ago...LOL). souldrops are kinda okayish 22 souls gave me 3 4* so on the low end but still okay for me...
but BNW isn't fun at all. it takes too long, it's too expensive and the drops are still crapish, wasted feature for me...cannot see a reason to farm it after i get enough immunity talis. really unfortunate after 1 year of development...
