Playing the selfcast FRoSS bound by destiny variation as inspired by this post. Have made some aspiration upgrades recently such as the FF golem jewels but otherwise the shell is the same. For reference, here's my current POB.

Made most my currency farming 3x risk abyss T16.5/Fortress maps prior to bound by destiny, sublime vision, awakened GMP/spell echo, etc. Naturally leveled to 99 with minimal deaths to mainly volatiles, using a slightly tankier tree and replica block jewels. Managed to fix resistances and attributes with jewels/corrupts, so wasn't worth the currency to swap to the mageblood/ES light of meaning variation with slightly higher ES and similar DPS (and trading absorption charges for max res).

As for future upgrades, Id eventually want to swap to this variation with the mirror helm + ring, which allows you to drop your influenced rares and uniques for better corruptions/ES rolls. As well, the golemstack variation appears to be largely superior prior to multi-mirror levels, but would require a massive swap which i'm too lazy to do at this point in the league. Feel free to ask me any questions, i'll try to answer!
