Piercing and Critical damage
There are two types of attacks that have special rules: Piercing damage and Critical damage. Creatures in Appendix C: Dungeon Denizens occasionally have abilities that deal one or both types of damage.
Critical
When struck by Critical damage, mark Injured. If already Injured, mark Death’s Door. If you are already at Death’s Door and take Critical damage, you die.
Critical damage towards enemies reduces their Health to 0. They are at Death’s Door.
Piercing
Piercing damage cannot be absorbed by armor, shield or helm. A successful Piercing attack always causes a Wound.
Piercing damage toward enemies bypass their Defense and directly reduce their Health (see below).
