act 5 final chapter ultron fight
dont use any 4* unless its a star lord r5/5 max lvl and awakened. Dont use any other it will be a waste of revives. Use the following 5 stars: Blade dr voodoo, mordo, spider man (stark), magik, hyperion, nightcrawler, archangel, ghost rider, star lord, amd gwenpool (r3-r4) better to be awakened lvl 40 and up. You wont have to revive your champs as much. Next, i did the fight tons of times and I learned that ultron attacks first instead of blocking so block and the key to this fight is to do as much heavy attacks as possible to break his block then use your champs (the ones i told you) skills to get as much damage in. I have farmed this boss about 10 times now and have the Elders Bane badge on 2 differ accounts(beside my main. TRUST ME ON THIS ONE
