You are a tough guy. When other characters would get impaired due to damage taken, you really get going. Ignore all Impairment for wounds.
With two schticks in Guts, you get an Action Value bonus instead of impairment when you are hurt. This bonus is +1 at 25 Wound Points and +2 at 30 Wound Points. You still look mangled and take Death Tests as normal. Out of combat, you limp about and generally are half-dead.
