So brimestone also helps a lot, for it cause a lot of passive dmg which means the boss passive triggered at the end of the turn (when brimestone kicks in) is much higher. (unlike for 3PK team, timing is not really an issue). And the similar situation for this Kuzard team is worse – timing is totally messed up. If you use a max HP dps in 3-PK team, you could easily fail. For 3-PK team, this is not fatal unless it is the 40% one that could one shot PK – yet even so, you still have Geo up for two more turns, and he can finish the boss. If any of the team member goes w/o block dmg during a turn, and the next move is an active dmg, the boss passive is triggered. For no matter what set up / speed (even the 3 pain keeper team), there will be some “dangerous” turns (or two, like 12-14-22-24….), when during the turn, a PK is without block dmg. The key is to make sure passive dmg triggers the boss passive at the END of each turn.

Savage Kreela, Fury Fahrakin, Toxic Maneater, all in pure DPS gear.

Gear is the general restriction here, most probably don't have the gear to make this a 1 key team. It's a very accessible team (champion-wise), they're all epics besides Kreela who is a fusion.

Unfortunately, Geo is a must – even for the 3-Pain Keeper Team. 2 Maneaters, Kreela, Geomancer, Fahrakin.
