  • 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.
  • 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.
  • 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.
    • Keremet can be Silenced. He is highly resistant to stun, sleep, and Blizzard spells.
    • Like all Corse, Keremet can Charm members of your party with the Danse Macabre TP attack. Charmed party members MUST be slept. This fight is pretty tough as he has a nasty AoE paralyze move and can charm multiple targets.
    • 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.

NOTE: If a party member has fallen during the fight with the Professor, refrain from using Tractor as it will cause the player to zone and the NM will have to be repopped before they can get their key item!
