I guess AS is all about picking the right team comps
I'm a fan of DoT characters actually, saw first stage has a buff for DoT so decided to give it a try. Also being monkey-brained, I haven't really paid attention to how the new monkey-TVs work and just thought well AS is the playhouse for Firefly team as always, let's just use them for second stage.
(P.S I was figuring out the buffs and gimmicks for this AS cycle as I was attempting my difficulty 3 runs just because it's been a long week and I can't be bothered to read all the texts)
This is probably the first time I got a higher score on the Difficulty 4 compared to my Diff. 3 run. Firefly team on the first half is just such a game changer, some well timed Gallagher Ult and the Fire implant from Firefly just bypass any needs to waste turns killing the ice pillars.
I use the "Cheat Sheet" for the second half, I thought Sunday would just constantly buff Acheron with that, but in hindsight maybe the Ultimate DMG bonus could be a good option as well.
