Yes. Two in fact.
One, is right at the start, after you get out of the cell, and kill the goblin. There are 2 bones in the upper right corner behind the table. Take the bone that is positioned on the left and use it 10 times on the chair. Meaning, don't hit the chair 10 times with it, but double-click the bone and then mouse-over to the chair and click on it. Repeat 10 times. It will fill your inventory with all kind of loot, plus some tokens. "Equipping" one of the tokens (by pressing the button that uses an item, eg. equip a weapon), causes a different effect. One of the tokens levels you up as well.

Second way, that will make you completely godly, is the MAX rune cheat. This will give you a lot of skill and attribute enhancements plus a lot of points to actually spend on skills/attributes and will also fill your magic book with all runes.

The first cheat he shows of is MAX. Be warned, its a bit tricky to do.
