just use cheat engine and buy the FP stuff o.ö
you can also buy alle equipment with FP stats
Tutorial:
simply change the ID of the standart effect to the FP ID
like:
1102303003 (shirt standart ID +5% attack) ---> 12002 (shirt FP ID)
if you've done this you can just buy a shirt in the shop and it will have FP stats
IMPORTANT!: Restart The Game If You Bought Everything Otherwise It Will Crash!
