I've been searching all week for some form of hack. All I've been able to find out is that people seem to think the battles are hackable but of curse things like orbs and stamina are server side.
I'm not a programmer but I did find this on another forum
"instead of the data being stored in a DWORD (32-bit), it's essentially stored in a QWORD (64-bi). Changing the difference immediately reverts back to the true value, you need to use XOR between the two 32 bit values (DWORD) to get the true 64-bit value (QWORD). If you search QWORD using game guardian, you can get the difference, but you can't directly edit it- you have to change the actual DWORD values, and I'm not sure how to do that."
Not sure if that information is correct but maybe if it is it'll help set someone in the know on the right path to figuring something out.
