Regarding uber trist and ancients: they are not an issue, I've done both several times now with a blood boil build.
Demons used: Cursed P8 urdar or lancer. (Others may work too, haven't tried it.
Kill bosses one by one.
Uber Trist: Port your demon + 1-2 goatmen on the boss you are killing, use sigil lethargy. Resummon goatmen as needed. Use blood boil freely when there are adds you can engorge. Use hardly at all when not, you don't want your demon to get killed.
Uber ancients: Same procedure, just without engorge. You can use blood boil as long as your demon doesn't drop too low, resummon goatmen when they die. If you are squishy, you may want to keep the distance and port your summons to the boss you are taking on.
Gear used: Obsession, Enigma, Magefist, Soj, Soj, Arach, Baalos, Wraithstep, 3demon 20fcr circ, 3demon 100 life amu, Anni, torch, 9 demon skillers
Yeah I did ubers a couple times just to test it out. The demon alone could kill them if I separated them, and even when they were grouped up it was more an issue of the mana refill needed because defiler linking them makes the damage per cast so high it only took 2 cycles of a full tank, so the only bottleneck in the whole run was the loading time. And the best way to improve the build was to do the "unpack your data files so they don't have to decompress" and then there's no risk of dying at the portal. But it is one of the few areas where damage is so high a demon like spearwoman could risk dying, maybe I was having an easier time because I was using a conviction demon at the time and that means it overrides mephisto's aura
Actually its another consideration in the "conviction merc + holy aura demon vs insight merc + conviction demon" debate that there are areas like ubers & herald 5 where your merc
will die, and that gimps your damage output. Plenty of herald fights where my merc died to some stray hits but demon could infinitely tank them, and then an infinity merc means you lose conviction.
Obsession for this build is big no no as you go higher end.
This build innately requires you to telestomp and weaken curse from obsession will erase amp curse very very frequently.
also on the builds where I have done obsession, like ES lock, I found weaken barely ever overwrites amp curse, its a pretty negligible factor. Almost all the enemy attacks are hitting your demon rather than you, and even with 15% chance to cast decrepify on ars baalos I see it pretty rarely.
I was concerned about that CTC being an issue for ES but after testing it I found its not a problem in the slightest
