Valpurus gave valpurium hand

Not sure if this is a bug. But if Valpurus is pleased with you, you can get new limb due praying.
Wiki says, that he won't do this.

Wiki might be wrong about this and valpurium limb sounds pretty rad!

Indeed. It's very unusual for a weak hero to get a couple of hundred arm strength points early in the game.

Unfortunately, I think you will have to deal with kamikaze dwarves soon.

On that attempt, my char has starved to death.

I honestly don't know how I ever did artifical limb wins. Whenever I try them now I can't handle the danger level anymore

It requires luck and only doing the limbs once you have a good survival kit already assembled.

It's really fun, slaughtering through most enemies easily, but yeah, the other half of the time I have to keep running from some unique of übermonster.
