To finish all 300 floors of Fey you need just 2 scrolled team.
Control team
* Ripekas - must be tanky and have at least ⅔ of recommended accuracy * Zhar’loth - must have highest attack on the team, stun set helps a lot as well * Gardrus * Theodore * Iola
All heroes must be scrolled and must have required accuracy for the floor (except Ripekas whose focus is on enough tankiness)
As you can see the requirements are pretty mellow though good accuracy is needed for all heroes except Ripekas. Ripekas can have lower accuracy and still land enough debuffs for this to work.
The strategy works the following way:
Opening with Zhar’loth who will go first to land Fear on the most annoying enemies on the battlefield (this likely has to be done manually or otherwise it will be casted on just nearest enemies)
Gardrus ultimate to push all enemies to the back
Ripekas ultimate to push down ultimate gauge and debuff
Wait for Ripekas to cast his battle skill (enemies will jump)
Then after 3 seconds cast either Iola then Theodore (or other way around)
Then Zhar’loth ultimate will be restored an you can cast Fear again
Repeat from 2 until all enemies are dead
Theodore is MVP here because he will quickly restore Zharloth ultimate - just make sure to have 3 second delay between control applications
It works on every stage except boss stages
Special considerations
If you have jumpers then put a high defense / low hp hero in front of Gardrus so he can push them back at step 2. Play with positioning if needed. If you have good skill haste you can sacrifice Iola but better just drop her below needed accuracy and load her with defense just in case (she will likely be lowest HP on your team)
If Ripekas dies too quickly you can give him 3-sec immortality Mythic, drop him further below recommended accuracy, and use defense/hp buff food. After he survives for one cycle he will be fine for the rest of the fight without a dedicated healer.
Premtsa somewhat counters this team so you need to play with gear to make everyone tanky enough to survive her specters. This might make some stages slower but regardless of your build you can make it in 10 minutes
Boss team
Use 3 must have heroes + 2 ideally summon/frost damage dealers:
Eurion - super tanky
Torrin - I recommend scrolling him to have easier time
Thia - must be scrolled for later stages
Premtsa and Lelwanis are the best but you can get away without exclusives (Look at Usha/Rava, Zadok/Istarian). Just make sure your dps are scrolled and have decent talents for the stage.
This is an auto team. My Torrin was not scrolled so he had Hourglass artifact but I recommend you to scroll him. Use food buffs if you run out of time
