The armour and shield can be used as components at the forge to create one of the following items at a cost of 3,000 gp and 2 weeks worth of work:

  • Thorned Greatsword. Is a +1 Greatsword that can cast lightning bolt once per day.
  • The King’s Mirror (shield). Is a +1 shield that allows the owner to deflect any targeted spell – any spell that requires a to-hit roll – as a reaction. If a spell targeting the wielder of this shield misses it is automatically reflected back at the target.
