Hardness is an attribute of weapons and armors.
- Weapon's hardness increases its chance to damage the enemy's armor. Armor's hardness helps your armor resist damage. [1]
- Damaged armor will have reduced DR (damage resistance). Damaged armor can be repaired via Crafting or Blacksmith. [2]
- Each "better" metal increases hardness by 10 points. There are also crafting techniques to improve hardness.
- Chance for weapons to damage armors is governed by ADC (Armor Denting Chance).
