p121 Pain Resistance
"reduce all Injury modifiers (to Action Checks and movement effects) by 1 point (to a minimum of 0)"
Does it reduce both the Standard Dmg Mod and Fatigue Dmg Mod?
OR does it reduce their sum by 1?
i.e. Without Pain Resistance, if your Standard Damage Mod is -2 and your Fatigue Damage Mod is -1, is your total Damage Mod -1 or -2 with Pain Resistance?
