In Ars Magic 5th I am not able to find how combat works for a character with weapon and shield.
Attack total is:
Dexterity + Combat Ability + Weapon Attack Modifier + Stress Dice
Defense total is:
Speed + Combat Ability + Weapon Defense Modifier + Stress Dice
If a character fights with a sword and a shield, does it add both Defense Modifiers? Is the same done with Attack Modifiers?
