To increase AC, you can wear items of Armour (1 per body area)  Each item of Armour has an AP rating. All worn items of Armour produce a Total AP number.

Armour Point Bonus (APB) is your Total AP minus half (rounded up).

Your AC stat is calculated using the formula 12 + APB + Dexterity Modifier.

If your AP exceeds the total of your Strength x 2, Or the total of your Strength Modifer + Dexterity Modifier – you will become Encumbered.

If your AP exceeds BOTH the total of your Strength x 2 and the total of your Strength Modifier + Dexterity Modifier – you will become Heavily Encumbered.
