For Axe, the base chance is 20%, and the damage is 1d6+your damage bonus (I will be handling the rolls and such behind the screen, as it were)
Shield has a base 15% chance.
Grapple, head butt, kick, small knife and fist skills are all down at the bottom of the sheet (Grapple is a 25% base chance)
Armor gives damage reduction - you wold have leather and ring type armor at best, which deflects 5 points of damage each time you are struck. Your shield stops a lot more damage (25 points for the standard iron reinforced shield used by your people), but only against one attack per, and you must succeed at a shield roll to use it. Damage in excess if the shield rating destroys it (damage above you armor's armor rating does not detroy the armor. (again, unless there are objections, I'll just handle all of this)
Not a problem, BTW (plus, I don't think Taitzu has this book...)
