Fastest way to T4?

Every season I always play every class. The fastest way I have found to get to T4 so far is:

  1. All classes level 1-60 I play BASIC skill with Adaptive, Moonrise, and Rapid Aspect while using 2-hand weapon. Clears everything fast to level 60.
  2. As soon as I reach level 60 I go to Pit and clear T2 with same setup easily. Change to T2 and farm with same Basic skill till I get all my Ancestrial Uniques for whatever build I want to play.

So the big question is “Where is the best and fastest way to get Ancestrial Uniques?” I usually just run the league quest line and eventually get the uniques I need but is slow process.

as for s7 - undercity on the torment level you can clear.

Undercity S7 was very underwhelming for me this season. I thought it would be great but I didn’t get any useful upgrades at all. Alot of uniques dropped but if it was ancestrial it was always useless stats that I didn’t need for whatever build I wanted to work on. Maybe the RNG gods hated me this season. Will try it again in S8 and hope the RNG gods will be in my favor this time.

Target farm Uniques for your desired build from the Initiate Bosses. Even in T1, they’ll have a decent chance of dropping at least 1 Ancestral item, even if it’s not for your build. Those can work as temporary gear pieces until you can get a decent GA Legendary.

Thanks for the replies. I’m thinking Initiate bosses for S8 may be the way to go. With the changes to them I hope they didn’t nerf the drop rate for keys.

I remember, in campfire chat, the devs saying they want to normalize building with normal uniques and then farming belial for the best source of ancestrals.
