3rd ascendancy - where to farm LOWEST monster level barya ?

So, which map in campaign gives the lowest monster level Barya for 3rd ascendancy, aka 3-floor ?

anywhere lvl 60 ,so the end of act 6 cruel

Unless they changed it this league, there's an Atlas tree node that gives specific biomes additional drop chances for different things. I think it's desert biome that gives increased drop chance for barya and ultimatum. If you're far enough along in mapping, you could grab that and do T1s on desert nodes. I got lucky last league and managed to drop a 3-floor barya in just a couple of maps.

nevermind, just finished ML 65.
