When a Spell, Elemental, or Poison qualifier attack strikes a shield with this Ritual, the bearer may call Resist by expending a Strengthening charge as though the item were shatterable and hit by a Shatter effect. A Shield with this Ritual may be re-Strengthened by a Blacksmith to regain additional uses of this ability, unlike most enchanted items. Note that this Ritual still confers normal indestructibility as per other duration Rituals.
