Rise of Krypton Heroic 7 Tier 5 Clear (14.6.25) - Injustice 2 Mobile (Free to play)

Happy for FIVE ONE SHOTS, esp on one of my most hated solo raids. I reckon this solo raid to be one of the most challenging ones. Boss COW Batman has chaos, and is immune to crit, lethal, stun and freeze. Currently, this is my ONLY build which I can use to one shot the boss. So I won't be able to use this team to fight boss COWS, unless I wait for a day. Aside from being SUPER TANKY, his chaos mechanic makes him super difficult to deal with. His Sp2 stun bomb, in particular, is super annoying. If hit by one Sp2, it's very likely that the hero GG already, esp during the final minute. Boss JLAM negates damage from Sp2 and Sp3, but remains vulnerable to effects. Boss Nightwing has increased effects on stun, longer duration, and auto crits. His specials also have a chance to trigger stun. Boss COW Superman is immune to stun and freeze, and has extra high defense towards crit, DOT, and armor pierce. He does not have special block. His Sp3 now costs 5 (from 1) power bars, and Sp1 now costs 3 (from 4) power bars. He also removes all buffs on your hero, and converts them into DOT to hurt you. I am a FREE TO PLAY player, so I generally work with whatever is given free.
