found the pay wall. Can't beat reptile boss unless you pay money. Nothing like injustice mobile. Where the bosses were doable without it. Not where you could buy gold characters if you saved enough coins. Nope you have to save souls which are incredibly harder to get. Not to mention reptile has ridiculous combos that deal half or all of every character's health bar at this point, that completely kill any character you have along with the fact that if kitana dies, which she will cause everyone else you have will just die instantly. This is poor design and nothing like injustice. He's level 26. It's impossible to be that level through just purely playing the challenge towers and it's impossible to have a character strong enough to beat him. So they give you a loaner level 17 kitana. Cause she'll certainly do enough.
Besides all of that. He literally blocks and reads every single one of the times you try to attack. This is a pay ceiling at its finest.
