Returns armor and passthrough of a unit's equipment (uniform, vest, helmet) on a hitpoint:

player getHitPointProtection "HitHead"

returns:

Array: [Number: armor, Number: passthrough]

No hitpoint informed should return same as [getNumber (configOf player >> "armor"), 1]. 1 is constant in this case:

player getHitPointProtection ""

returns:

Array: [Number: armor, Number: 1]

Use case: getting "real" damage inflicted to hitpoint, before passthrough/hitpoint spread/armor, so the hitpoint that took the initial impact can be determined during HandleDamage event.
