The Juggler is an enemy that appears in the Fiendlord's Keep in 600 AD.
Jugglers operate on a physical/magical defense concept. Attacking them with physical force increases their physical defense, but decreases their magic defense. Attacking with magic does the opposite.
If there is an Outlaw in the same battle, the Juggler will respond with a Fire Whirl Dual Tech counterattack if the Outlaw is attacked. If the Juggler is attacked, the Outlaw will not respond.
