[Free to play: Injustice 2 Mobile] - Solo Raid Dark Nights Heroic 3 Atrocitus

Finally down this atrocious boss! His DOT from specials hurts badly, and has power drain. But it isn't as bad as his Chaos mechanic. As usual, cut his life by a percentage first, then use teams like BNCW with solo heroes to deal with him. I am generally a FREE TO PLAY player, so I don't own powerful artifacts like beta club, sword of sin & salvation. I work with whatever that is given free.
