Beware, the Dragon King!
This monster boss rules the Brave New World Dungeon and starts with a damage-absorbing shield that must be dealt with before it can take damage. Take too long, and he resets the health of his shield! Depending on the dungeon being fought, the boss will either have a Titan Shield (need to do a certain amount of damage to break), Force Shield (need to do a certain amount of hits to break), or both a Titan Shield and a Force Shield.
The Dragon King will also change what skills he uses depending on if his shield is broken, and will use a wide variety of debilitating status effects, from Grievous Burns to Marks to Doom, so be prepared!
