Aht Urhgan Mission 13: Lost Kingdom

Walkthrough
Nashmau
 * Trading Pyopyoroon (H-7) a Vial of Jody's Acid triggers the Mission 13 cutscene.
 * After he gives you the key item Vial of Spectral Scent, take the west exit of Nashmau to Caedarva Mire.

Caedarva Mire
 * Go to the cemetary at (E-10), where you find a target point called "Jazaraat's Headstone".
 * The headstone will need to be checked a total of three times:
 * 1) Check the headstone once to trigger a short cutscene; everyone in party must check it once for cutscene!
 * 2) When everyone ready to fight, have one person check the headstone again to spawn an NM Jazaraat (Fomor)
 * 3) * NM Jazaraat has all Fomor weapons skills and the two-hour Wild Card.
 * 4) * Trivially easy for a party of six Lv75s. Is easily duo-able by 75 NIN & WHM. Soloable by a 70+ BST but he hits fairly hard (I recall a critical for 371 at level 75 with an Earth Staff). Also duo-able by two 75 SMN without bloodpacts, using Carbuncle with Carbuncle Mitts.
 * 5) * Be careful not to do this fight at night because the Guard Skeletons will aggro.
 * 6) Check the headstone again to recieve another cutscene and the key item: Ephramadian gold coin.
 * 7) * Do not zone out of Caedarva Mire without obtaining the key item!
 * 8) * If do not get the key item, you will need to fight the NM again.

Game Description

 * Mission Orders: Pyopyoroon of Nashmau has advised you to head west to a place with many "stooones" to find a special "ghooost." Perhaps it will lead you the ghost ship...
