Found this nice spot with my friends and didnt find any thread with my farmroute.
You need a barb or monk tank and i recommend more than 1 mio dps buffed.
You want to look for A4 bounty "Clear the hell rift". The tank just rushes for lvl 2 rift rest of group teleports when he is there. The level 2 rift is easy to clear there is no elite, only Hammersmahs can spawn. We did it like 3 hours today and he spawned 5 times. The bounty gives 420k gold and 65 mio xp on T6. We need 60 to 120 sec to complete the bounty. Disband party and everyone starts game and looks for bounty. In full group usually one member gets the quest. This is the part that can take some time because of rng.
There is also a spwanrate of 40% for a cursed chest in the Rift lvl 2. The event rewards 200k gold and 20 mio xp and is a 70% chance to start kill all enemies in time event, so also easy to complete. Sometimes an elite spawns, then we skip it and leave game. I recommend to open chest after completing bounty, because killing the elite will take ages.
Additionally almost every 5th run a pool of reflection spawns in level 2 rift so you get even more xp.
We all got at least 2 legs per hour from chests.
Hope you guys have fun with this spot. Best spot I know of.
If u have any questions or sth is unclear let me know.
