The Ultimate Lair is unlocked on Day 13 if you managed to complete all 5 Main Quests (this includes the one with Sazh and Dajh) and at least 40 of the 66 side quests (excluding those from the Canvas of Prayers), at which time your trip to the final dungeon will be postponed to the 14th day and fulfilling the requirement for the Beyond Thirteen trophy. If you didn't go straight to the lair from the Ark, the red cactuar warp point in the Dead Dunes (Temple Ruins East Gate) will take you there.
In total, the special dungeon has 33 floors, with each floor inhabited by a Last One (the Omega version of a monster) . Each one of these monsters will drop an accessory or weapon upon defeat and also activate the warp point on that floor allowing you to go deeper into the ruins. Also note that any Last One that you've defeated outside the Ultimate Lair will not appear in the ruins, leaving the floor where it's supposed to be in empty. The warp points also allow you to skip up to 3 floors at a time. which is good given that the clock doesn't stop during combat nor can Chronostasis be used.

Ereshkigal has 7.5 million HP so do yourself a favor and hug the wall then circle around behind the creature to score a Great preemptive strike. Equip three schema with the highest ATB and ATB recovery speed. For abilities equip Thundara and Aerora across all schemata, along with Poison and also Skeleton Earrings (Rafflesia Omega, found on floor 27 of the lair drops this accessory).
This beast must be staggered 3 times before any real damage can be done so spam Thundara and Aerora until you achieve that goal. Once you do, throw Poison until it sticks. At this point, the ailment will do most of the damage and you just need to help it along by dealing all the damage you can and survive. Recast Poison right away when it fades. Bring a mix of Phoenix Downs and X-Potions too.
Defeating this special boss completes the Ultimate Lair and earns you the Monster Bane trophy. Ereshkigal also drops the Ultimatus Garb which will unlock the Holy Garb of Destruction trophy.

I hate Ereshkigal. I always confused whenever he's about to throw a meteor smtg at me but instead he's doing a barrier to protect itself. I was just wasting my time guarding then. So there's nothing wrong to skip this Ultimate Lair right. You can just go straight to fight Bhunivelze. Unless you want to complete that Last One Standing side quest hm.
Can I return to the lair after beating the game?
After you beat the game you unlock new game+ so you would have to play through the game again to revisit the lair
Physical attacks stagger him but it takes a lot of hitting and guarding
Well... I'm Not Unlock The Day 14
Not Defeated Ereshkigal.
I Hate Caius.
How can I stagger Bhunivelze (last form)? Any tips for the battle? What r the adventages of triggering a New game+?
Awesome guide! Thanks for all the assistance.
