Good catch...
i think that was not so difficult to notice... i'm very surprised that no one noticed before...
however i'have noticed another thing about ABTP "design"...
all pieces give same DB... except the cuirass, that give the DB of other pieces x3
i.e. if foot piece give 2DB, then legs piece, pauldrons, etc... all give 2DB, instead cuirass give 6db
then, if we want obtain a damage location table from this data, we can say this:
head, foots, neck, legs, shoulders,and hands: has 11% chance to receive hits (tot. 66%)
torso+abdomen (and back) has 33% chance to hit (adjusted to 34% so we have a total of 100%)
(i "played" with this numbers just cause i'm trying to make a house rule for localized critical damage, and then this data can be a "official" source for this..)
