Wounds are serious injuries you’ve taken; they are a long term gauge of how close you are to death. HP can usually be recovered quickly, but Wounds may take many days of resting to fully recover from (usually 1/Safe Rest).

Miks2 additions to cause players to take more wounds:
If reduced to 0 HP by a critical hit, you take +1 additional wounds (2 instead of the standard 1) If an attack that inflicts wounds would deal over half your max HP in damage, you take +2 additional wounds, or +4 if doing over your max HP.
