You can manipulate coins, defense and skill point by change one value with each other for example you have 1 mil coins so you can change your defense and skill point to 1 mil or vice versa:
Seach current skill point with double anonymous
Make some change to skill point so you get 1 result, go to selected address
Save a value 2nd line above skill point address. the one with dword value. So now you get 2 value, one is skill value in double and second is a dword value.
Locate coins value which is 8th line below skill point value address
Now you can change gold or skill point. replace each value to their respective value. double to double and dword to dword.
You can change defense with this method too or maybe other value that have same double-dword pattern.
I hope you understand my bad english.. lul..
