God Mode / One hit won't help, legit play itself can achieve One hit Damage (ScreenShot Below).
The Material can be change with Game Guardian but not the HardCurrency (Mkey, Rebirth, Dia)
Totem Level and Totem ID can be changed but it won't save the hacked Totem to Cloud, its just for saved game play.
The thing that I suggest to look for is "Remain" its a Reward Box where player need to get it from Shop / Once their characters is dead and choose "game over" > revive(rebirth) and they will get one Box chosen at random.
There is 4 kind of boxes player can get, Small (1mkey), Medium (3mkey), Big Green (6mkey) & Big Gold (9mkey)..
It might be server/client, but I see nothing and there is bug where we can keep the box forever.
Hope it's help y'all.
