The add/freeze keys will work sometimes but you will get stuck on that screen a lot of the time.
The unlimited mana does not work in pvp just pve. It will show you have unlimited mana but you really don’t and you will get the error 200.
The + dmg/def only works some of the time, I think it only does when you are hosting the game. To check if it is working switch on unlimited mana and see if your mana goes to 10. If it does turn it off and just leave +dmg/def on. If it does not go to 10 mana, turn everything off. i do this on every game.
