Durable weapons, found only in The Elder Scrolls IV: Shivering Isles, are special versions of normal Cyrodilic weaponry. As their name implies, they are more durable and valuable. Versions exist of every material type, from Iron to Daedric. Durable Arrows do not exist. All values are extracted from the base values of the weapon. Damage is calculated by the maximum level attainable, without considering perks, skills, active effects, spells, or item enchantments.
