This development was done for Dragoncoat: Shores of Haldun.
The Robe can be used to ready up to 3 defensive spells on it such then when struck it will automatically fire the prepared spells as a defence. If you wish to reset the robe you need to cast either greater dispelling or Mordenkainen's Disjunction on it though it automatically resets when it's use is applied. It has no properties other than restriction to wizards and sorcerers.
It maintains a status on it to reduce impact due to on-hit trigger invents which should hopefully be minimal for mage classes in comparison with others.
