Wounds

When falling down cliffs, running too fast down hills or when fighting you may or may not get hurt. The wounds will pop up under the affected bodypart under "Body" in you "Inventory".

Bad wounds have a chance of getting worse and eventually killing you. Severe wounds will kill you if not treated properly.

It's not true that several can kill you. I was have 1% of hp 3 several from 30min and don't die.
