Crimson Longinus
Legend
Unless the system tracks hit locations it doesn't matter and I don't even want it to matter. Your armour bonus, AC, whatever just measures the overall protection the armour offers and there is no need to track protection of head separately any more than the protection of the left foot. The armour may or may not include a helmet, gauntlets, greaves etc. It really doesn't matter. Some people might think helmet clashes with the visual style they want for their character and I don't want to force them to compromise that. I value amazing hairstyles over historical realism.
