Seethe is used as the rune of choice for Vengeance. In the armor slot in cube use leoric’s Crown. For companion use the bat rune. Also use Blood vengeance as one of your passives.
You also can use a gold build variant that will bump up speed, armor and life regeneration
Vault really isn’t a need in T16 as you’re dropping everything with one shot.
TBH I prefer UE for farming because it’s fast and when I blast a screen of mobs I have time to pick up drops for mats which I’m always ending up short of. For a pure speed clear (eg: Speed Racer) it’s gonna be GoD.
This is the reason I think UE Multishot is better at goldfarming as well. With Multishot you shoot forward, move forward, and pickup stuff as you move along. With Strafe, like with Whirlwind, you kill stuff as you pass by it and need to back up to pickup the stuff on the ground (Avarice Band mitigates this issue a bit though).
It’s nice not pigeonhole one set for everything IMO. I think gold/mat/NR farming UE will still reign, but bounties and straight keyfarming will be GoD.
also use lightning rune ricochet, bat, with an emphasis on speed and either goldwrap or chain of shadows. equip awareness passive because you’ll eventually get 1 hit (often especially if laggy)
In a proper T16 farming setup, you’ll be using avarice band, so you’ll definitely be picking up most, if not all, of the gold even as you’re blazing by with the high movespeed on GoD.
GoD is gonna be faster than UE without any contest. Sure, in a big open map, UE might be faster, but you’ll be farming T16 for hours. You’ll get bad maps at least 50% of the time, and the extra movespeed from GoD will help a lot.
I’ve long been using S6 for T16. I fix hatred problems with skill swaps (bat, punishment, seethe) because the extra toughness isn’t needed. I just really like the vault around like a madman/stop and pew pew play style, and I like the consistency of using the same build no matter what I’m doing.
