Lightbringer

How to obtain this mission
You will have to wait til the next earth day (Japan time) before you can take on anymore missions. After midnight Japan time occurs, zone into Northern San d'Oria for a cutscene.

Repeat San d'Oria Mission 1-2 or San d'Oria Mission 3-2 until Lightbringer is listed in the mission list. This will happen after repeating Mission 1-2 8 or 9 times.

Walkthrough
Talk to the king while in the castle. A cutscene will occur. After the cutscene, talk to Rahal to receive a key item.

Form a full alliance of level 65+. Level 65 is still borderline aggro to the weak mobs of Temple of Uggalepih, so they will need to carry Prism Powders due to the magic sensitive mobs in this place. A level 70+ character is safe from aggro.

Make sure a member of the alliance has a Prelate key (dropped off Tonberry Stabbers). Take Teleport-Yhoat and make your way to the main enterance of the temple.

Once you zone, take the right path until you zone back into the jungle. Keep going straight and you will zone into another part of the temple. After zoning, follow the right wall until you pass by a wooden gate. Shortly after you pass this, the path will split. Take the left path and clear the area. You will have to kill Temple Guardian in order to continue on. After the guardian is defeated, continue past that door that will now open and advance up the stairs if you have a prelate key. Once the prelate key is used on the door, keep heading south and take the left path until you see 4 doors on the right. Door 1 is the furthest down, Door 4 is the first door you will see.

Clear the hallway of tonberries and magic jugs. Now enter Doors 1, 2, and 4 and inspect the ??? for a key item. Once everyone is ready, have someone inspect Door 3. Once this door is inspected, 2 Doll NM will pop, Nio-Hum and Nio-A. They will not sleep, so have a tank and a damage dealer keep Nio-A busy while everyone else concentrates on Nio-Hum. Mages should have Barfira up in case the dolls blow up. Once both dolls are defeated, everyone should inspect Door 3 for a cutscene stating that Lightbringer cannot be found.

Return to San d'Oria and talk to King Destin.
