Ogdoad

{{Enemy
 * name={{PAGENAME}}
 * type=World Boss
 * description=Twin Heads Ogres are rarely born, and they are stronger and smarter than normal one-headed ogres. The rarest and strongest of them all is Ogdoad, also known as the King of Ogres. For a long time, he lived in the depths of a wasteland in Allan away from humans, but then he became extremely aggressive after the Day of the Eclipse. He has not yet shown up near cities, but he has been attacking remote village and unsuspecting travelers. Alarmed by the casualties that he caused, the Allan Alliance has offered a handsome sum of money on his head, and Mercenary armies are flocking from everywhere to defeat Ogdoad.

Recommended Mercenaries
Always halve the skill duration due to Ogdoad's 100% AGI. Skill level shown below are the minimum skill level for the desired skill of each mercernary. Effect may increase as skill level is higher.

*Note:Deomaron is recommended in other guide due to the decomposition effect able to be stacked. However the real effectiveness is still to be determined as the author does not have Deomaron to test his effectiveness.

If you have Themis and Velfern, you can cheese for ~20k points off Velfern's debuff-based fixed damage combined with Themis's stats enhancement prohibition stacked 9 times from Ogdoad's attack.
