"This shield, as tall as a man, is aptly named. With it, Phil Pious, a paladin of the Most Noble Order of the Radiant Heart, once held a marauding battalion of hobgoblin and kobold archers at bay till they exhausted their arrows. As the shield is almost as useful in melee as it is at range, he then slew each and every creature."
