To answer my own question and maybe someone else have same question.
It needs at least 3 gb space
1 gb for raw data
1 gb after installation
1 gb game data.. And after that. You needs 350mb game update
@DESLOKAT Why all feature except attack speed keeps kicking me to main screen, i did like in the video, active mod before battle, go to battle, before the result screen appear it kick me out imediattely?
@Nerozaki deactivate all features at the battle begins and not at the end.
All activated feature that are active while the games load and is for the complete battle active.
The deactivating is only to prevent the statscalculating on the end of the battle
