Act 4 completed woohoooo!!!!

There are a plethora of guides and tips in the forums to use. But my suggestion is for you to take your time; build up a roster of champions with a diverse range of utility.

Invest in the dexterity and parry mastery. Those are a must. Next is the willpower mastery. Everything else is entirely up to you and your play style.

Can you tell champs that you use for completing act 4

Doesn't matter much. I'm on 4.6.5. Here's my team :-
4* 3/30 Emma Frost
4* 2/20 Drax
4* 1/10 Blade
4* 2/20 Iron Man Infinity War
3* 3/30 Stark Spidey (Awakened)
Got through content easily, no problems except 4.5.1. Some potions here and there but otherwise it's not that difficult. I hope I take Maestro down tomorrow.
