I think I found a bug. Once you die or make a mistake or whatever, you can quit the game and then press the continue game button. This will respawn you at the beginning of that floor or where ever you saved your game on that floor.
It lets you check what random events are ( You save right before and then go into it. Then you see what it is and do this bug. That event will never change so when you go back to it after doing this, it will be the same. ) It also lets you test out builds without the risk of death.
