Stubborn Dredvodd

Notes:

 * Spawns on the barge ride from South Landing to North Landing (see schedule). Exact spawn conditions unknown. Believed to be 21~24 hour spawn but has been known to take more than 72 hours to respawn after last death.
 * PC (possibly other systems) users can see a slight glitch that will give away if Stubborn Dredvodd will spawn on the ride. Right after the launching animation from South Landing, when control is returned to the player on the barge, look behind yourself at the deck of the barge. You may see a large round shadow for a brief moment. If you do see that, Stubborn Dredvodd will pop on that ride.
 * Resting (or possibly standing) on the sides of the barge is necessary to get him to jump aboard.
 * Calls a pet wyvern, which follows and assists it in combat. The wyvern does not despawn when Stubborn Dredvodd is killed; it will continue to fight until defeated. He can resummon his wyvern if it is defeated.
 * Drops approximately 64 gil. Can be Mugged for 25 gil.
 * Casts Stoneskin frequently (his wyvern also casts Stoneskin frequently as well).
