WalkthroughQuote:
* Optional, but recommended - Kill Orcs and Gigas in Misareaux Coast or Meadows to lower your Fomor Hate. Check with Resauchamet at (J/K-6) of the upper floor of Tavnazian Safehold. Lower your Fomor Hate to level 1, where Resauchamet will tell you that you have a “good head start.”
"You are an adventurer... I can smell the dark blood of the undead as it drips slowly from your soiled garments. Beware, my friend, for you are not alone in your journey. Lost spirits lurk in the shadows behind you, waiting for their chance to rob you of your soul. Hmmm..."
LEVEL 1 "You still have a fairly good head start, but they will not let up until they have found you and filled your heart with poison and pain.”
*Fomors will NOT aggro.
LEVEL 2 “They are close, It is only a matter of time before you have fallen within their reach."
*Fomors will aggro.
LEVEL 3 "Can you not feel the hands that reach up from the bottomless depths of hell? Can you not feel the gaze of a thousand eyes, glowing red with anger and hate?"
*Fomors will aggro.
LEVEL 4 "The grip of evil is tightening on the very essence of what makes you who you are. Be forewarned, as it will not be long before you are confronted with a battle for more than just your life."
*Fomors will aggro.
"Oh, poor child! May the light of the Dawn Goddess lead you from the pitch-black depths of darkness!"
* Speak with
Justinius at (J-6) in third floor.
* Click on the
Walnut Door at (K-7) upstairs next to Parelbriaux for a cutscene.
* Head to the Iron Gate in the northern part of
Misareaux Coast (G-4) for a cutscene. After checking this, you now have access to Sacrarium
* This is the entrance to the Sacrarium. This area is capped at level 50.
* Traverse the Sacrarium maze until you find the Fomor. Note that the maze walls will shift with each Vana'diel day. Kill the Fomor until you get two Rare/Ex Coral Crest Keys. You can do this mission with only one Coral Crest Key, but it will be necessary to have an extra person to stay behind to operate the door.
* Note that it is possible for two Coral Crest Keys to drop off of one Fomor, though this is rare.
* Next kill
Keremet, a Corse NM. There are two hallways, each lined with 6 NM Skeletons. The Skeletons don't aggro and are weak, but if anyone attacks Keremet they will rush to aid him. Defeat all 12 Skeletons first, then pass through one of the doors at the end of the hall (K-8).
* Keremet is at the far side of the room. Wait for the taurus to wander to one side and then pull Keremet back through one of the doors into one of the hallways where the Skeletons were. Only one person should pull Keremet while the others wait in the hallway. You have 30 minutes to kill him before the skeletons begin to repop and aggro you.
o Keremet can be Silenced. He is highly resistant to stun, sleep, and Blizzard spells.
o Like all Corse, Keremet can Charm (Status Effect) members of your party with the Danse Macabre TP attack. Charmed party members MUST be slept.
o He has ice spikes which can be dispelled and an AoE silence move.
o A Beastmaster makes this fight much easier; a Blubber Eyes under Familiar does a lot of damage and pets are immune to Keremet's Charm. Two Blubber Eyes can duo Keremet.
* Kill Keremet and obtain the Sealion Crest Key (EX). Give it to someone who doesn’t have either of the Coral Crest Keys.
* Head to (H-7) in the Sacrarium and find a door at (H-7) with two keyholes: one LARGE and one SMALL. The first party member will trade the Coral Crest Key to the SMALL HOLE; you will hear a click. The other party member will trade the Sealion Crest Key to the large hole; the door will then open. You have a limited amount of time to trade the Sealion Crest Key after the Coral Crest Key has been traded, so make sure the key holders are both ready.
(Both locks cannot be opened by a single person!) You will keep your Sealion Crest Key, but your Coral Crest Key will break. If the Sealion Crest Key isn't traded quickly enough, you will lose your opportunity to get the door open, and you will have to get another Coral Crest Key.
* Find and click on the Wooden Gate at (G-8) for a cutscene. (You do not have to do this CS before someone pops + kills the Old Professor Mariselle with you in the party but you must get this CS before the ??? will give you the Reliquiarium Key)
* Head back out the locked door. If you do not have another Coral Crest Key, you can leave a member behind to open the door with the switch.
* There are six classrooms, three on the north side of the area of Sacrarium you are in and three on the south side. Each has a ??? in it. Check each ??? until you spawn the Ghost NM Old Professor Mariselle and his two Mariselle's Pupils.
o Old Professor Mariselle casts Sleepga II and Silence, and uses Ghost abilities. It seems to have a fair bit of regen, so continuing to keep damage on is important.
o It will teleport around the room a couple of time during the fight (every ~20% Verification Needed). It will despawn first, along with its two pupils then respawn randomly somewhere in the room (the pupils also spawn randomly, sometimes all three are far apart after a teleport). Even if pulled outside the room, it will respawn somewhere in the room again, so this way of avoiding Fomor aggro is not recommended.
o If one of your party hasn't reset fomor hate, you will have to clear the room first, as pulling Old Professor Mariselle out of the room won't work (it will teleport back inside and cast from far away).
o If everyone reset their fomor hate, don’t use AoE abilities to avoid aggro.
o The Mariselle's Pupils are weak. However, if you kill them, Old Professor Mariselle will summon more. They CANNOT be slept.
o DO NOT use Tractor, if you do then you will have to get the ??? and kill the NM again.
* Kill Old Professor Mariselle and check the ??? again for the Reliquiarium Key. Any ??? in any of the rooms will allow you to obtain the Reliquiarium Key.
* Proceed back to the locked door and open it with your second Coral Crest Key and the Sealion Crest Key, using the same method as before. Alternatively, simply have someone operate the switch on the other side.
* Head back to the Wooden Gate to end the mission.
* Once the cutscene is over, you will end up on the other side of the Wooden Gate, unable to open it from that side.
