To anyone who's done 6.3

Evangelionlovr

I'm working on initial clear, and I'm becoming increasingly infuriated. I keep dying to stupid mistakes, even against easy opponents. The energy cost being as high as it is makes it that much worse because I can burn all my energy just trying to get in a good groove. I'm currently on 6.3.3, looking at either the resistor path or unblockable finale. My champ options are as follows:
R5: Gost*, Sparky*, Domino*, CaIW*, Aegon*, Corvus*, Omega Red*
R4: Quake*, Morningstar*, GR*, Havok*, Magik*, Darkhawk*, Hyperion*, Hood*, Sentinel*, Colossus*, Warlock, Venom
6*R1: Rhulk*, Mephisto, Doc Oc, Psylock, Phoenix

* indicates duped champion

I've been trying to get through each quest only using 100-200 units worth of revives (be it two team, or a combination of a few solo and a team) I have little to no pots because I'm coming off retirement and they all expired. Is this an unreal expectation? Should I farm WS before I keep going, and if so, how much?

Magik and/or MS will wreck the resistor line, particularly if you have some mystic dispersion. Bring Colossus for Havok, throw in 3*-5* Emma frost for the armor power gain synergy, get to 20+ armors and spam that L1 for the win against Havok w/ Colossus.

Don’t get frustrated over self-imposed limitations...

MS, MD3 or MD4, L2, good game.

For the resistor node you could use a duped Ronan, even at rank 3 it is too easy

You definitely have the roster for it, maybe you're just a bit rusty if coming off retirement?

I used Seatin's completion guide for the easy paths, sounds like you're on the right path for 6.3.3 and you got Warlock, Havok and Colossus for the Havok boss.

100-200 units per initial path is not much in my opinion, don't beat yourself up you can easily do a completion of 6.3 with that roster
