Save Scumming, Farming Hero Traits, Alt-F4ing. Backing up saves on Legendary. Keep Gotrek forever trick.
I've probably cheated nearly every way it is possible to cheat in this game, but I don't recommend it.

You want something, it's hard, you cheat, then you don't want it any more. Victory tastes like ashes.
You want the game* to be HARD.
