Shield of Dragonkind
This type of shield is made of obsidian with a trim and dragon head that matches which type of dragon its modelled after. For example, a Shield of Red Dragonkind has a golden trim and the shape of a red dragon carved from ruby mounted to it.
As a standard action, you may speak the shields command word. The dragons head animates and uses its breath weapon in a 15ft line or cone (as per the base dragon). All creatures in range must make a DC 20 Reflex saving throw. On a failed save, the creature takes 6d6 damage and half as much on a successful one. This can only be used once per day.
While wielding this shield, you have a +3 bonus to AC and a 5 resistance to the element associated with the base dragon.
Be warned however that a true dragon may see this shield as an insult!
The type of dragon is decided at creation.
