Drygon (The World R:2)

This Dragon is a particularly dangerous one. For it is a Boss Monster, and mostly found in level 30 fields. His Area of Effect attack is particularly brutal, because it has the potential to hit all party members for tons of damage. The best thing to do here is, if you have an Awakening open, then use it, and pound it into oblivion. His attacks aren't fatal, though a Harvest Cleric would be best used in this fight.
