Hey there. Thanks for the message.
As always, whatever works for your table is the right way to go, but here's how I do it:
- There's no negative HP: whatever the damage you take, you can never go below 0. Being at 0 HP means any damage received is a new Horrible Wound. If the Wound rolled doesn't make sense, you get the next one on the list. In my experience, it's pretty dicey to survive more than two Wounds in the same fight.
