What is the fastest way?

Farming low 60s and convert certain amounts or is it better to farm in the 50s to get mats for 1 - 8 and then go and fsrm for 9-12?

Still trying to figure out the fastest way to do it.

My char is not the best by the way. I can only beat (not farm) Pit 92 max. atm, so high pit farming is absolutely not efficient for me.

If you can beat 92, you can farm 80 in 3-4 minutes.

Kind of. Boss takes 1 or 2 minutes for me tho.

do any level that takes you around 3-4' to finish. convert mats later on as you need.
