Use a text editor such as notepad to edit the "Init.py" file in the "data" directory in the game folder. Add the following lines at the bottom of the file:

def CG(gold = 1000000):
Send(CheatMessage("c_SetGold("+str(gold)+")", Vector3.ZERO, 0))

def CSE(se = 1000000):
Send(CheatMessage("c_SetSoulEnergy("+str(se)+")", Vector3.ZERO, 0))

def CP(p = 1000000):
Send(CheatMessage("c_SetPrestige("+str(p)+")", Vector3.ZERO, 0))

def CSP(sp = 300):
Send(CheatMessage("c_SetSkillPoints("+str(sp)+")", Vector3.ZERO, 0))

def CAP(ap = 1000):
Send(CheatMessage("c_SetAttributePoints("+str(ap)+")", Vector3.ZERO, 0))

Doing this will add 1 million gold, 1 million Soul Energy, 1 million prestige (until you place a prestige gimmick), 300 skill points, and 1,000 attribute points. Note: This only works on the unpatched version of the game. Once the game is patched, this python script is replaced with Lua scripts.
