This is hands down the official abyss dream team. They carried me through at least 7 floors from 109-120 with ease & without the mental anguish that almost always accompanies taking on this task. Best tip I can offer is to build this team immediately if you are working through abyss, you won’t regret it. 

Usual builds: kitty 236 speed 195 resist on war horn.tama 230 speed on potion. a.ras 210 speed full tank, 90 effectiveness on adamant shield. taranor *** 0 speed , full damage, destruction. (I used rage maybe 2 times) on symbol of unity.

P.S. Before I attempted any floor I always watched videos of other peoples clears to hopefully save myself having to make countless attempts & always saw they had damn near impossible to match *** tier gear stats which was incredibly discouraging for me. I used a lot of the common teams per floor but with nowhere near those gear levels & still finished them all. Just thought I’d throw that in for anyone who‘s already given up because of that same concern. Hope this helps & good luck to everyone!
