Nick Fury is great, you want to spam special 1 to keep those charges above five and do m-l-l-l-l to get 2 furies per combo (two mix master evades that Fury prevents) When he's in real form, do 1-2 special 1's and you'll never be evaded. Stealthy will work well with his slow, idk if it will give you fury charges tho, if so do m-l-l-l-l again to maximize that fury gain.When doing this you also want to wait till the end of the parry to throw the medium so that the node affects all of your light attacks. AA is a decent option as well. If you play slow and safe with NF and Stealthy you should be able to clear the path. I used Falcon and Hitmonkey r4 and 100% that quest without too much trouble, so your champs should be able to do it too! Patience is just a big factor I think. Edit: Venom ofc is a really good option, I do like to use champions who can make use of that fury though because it makes the quest so much easier and fun. If stealthy isn't gaining furies and or you don't love him, I'd honestly trade him out for BWDO. Ideas from BuddyDClown and DeaconVelvet.
