  • New armor attribute: generic.armorToughness
    • Damage formula is now damage = damage * ( 1 - max( defensePoints / 5, defensePoints - damage / ( 2 + toughness / 4 ) ) / 25 ), i.e. increased toughness means less armor defense point reduction from strong attacks.
    • Diamond armor has toughness 2, all other armor has toughness 0. A full set of diamond armor, therefore gives a toughness attribute of 8.
