To avoid crash in android change character code for golds only. Changing the character value of a bronze character causes the game to crash in Faction Wars and Battle mode. Another thing is to edit the character value outside kollection. Do it in the main menu to avoid crash. Be very careful also if you edit the wrong id or give a blank id a character code you might end up corrupting the cloud save/game making it to crash and become unplayable. Speaking of which, you will then have to create a new save game and start all over.
Can someone tell me how to hack account xp value to 51 please?
Boss cards have special abilities like damage boost etc and are harder to beat
