The Great Gubal Library
Template:Dungeon Infobox "Built by the learned men and women of Sharlayan, the Great Gubal Library is the grandest repository of knowledge in all of Eorzea. Lining its towering shelves are tomes beyond count, gathered from the farthest reaches of the realm. Like the city-state, however, the library was abandoned by its caretakers when they fled to their motherland in the face of Garlean invasion. And now, fifteen years since its doors were sealed, you will be the first soul to set foot within its halls. Your destination is the forbidden section deep within the library, where lies your objective: the fruits of Matoya’s research on the aetheric converger." — Game Description

Demon Tome
The Demon Tome is similar to the Demon Wall in Amdapor Keep, with a few added skills.
- Like the Demon Wall, the Demon Tome will cast an AOE down the middle of the room, then the sides.
- As he is between casting the two previous attacks, the Demon Tone will also cast Dark Blizzard III, a circle AOE that will target a random player.
- The Demon Tome will occasionally cast Disclosure and "begin to glow." This signals that you need to run along the sides of the arena to the backs-side of the Tome. Anyone on the wrong side of it when it closes will be killed instantly.
- The Demon Tome will cast Words of Winter, an attack similar to Shiva's ground freeze - when the ground is frozen, you will move a certain length in the direction you attempt to use. Unlike Shiva, this is not all the way to the edge of the arena; it is a matter of several yalms.
Byblos
Byblos is a book demon, and the second boss of The Great Gubal Library.
- At intervals, Byblos will run to the center of the book that summoned him and become invincible. Shortly after, two books will spawn with adds in them. Kill the adds quickly. When they die, they will draw a tether between them and a given player (like the ice, fire, and lightning orbs in the Scylla encounter in Labyrinth of the Ancients. Draw this orb into Byblos to break his invulnerability.
- After one invulnerability phase, Byblos will begin spawning clouds of oil fumes around the room. These will cause 2k damage when you run through them, so take them in turns, carefully, to keep them from stacking up.
Everliving Bibliotaph
The Everliving Bibliotaph has a few ground-pattern AOE attacks in addition to:
- At 3 intervals throughout the fight, Bibliotaph will begin casting Void Summon. Platforms on the ground will light up, and they will need a certain number of players to stand on them in order to cancel their summon. When one light on the platform is lit up, only one player is needed to stand on it to cancel the summon. When two lights on the platform are lit, two players must stand on it. When three lights are lit, the platform needs three players. Before this fight, figure out who will go with who for the first two phases, and plan to run all together for the final (three-person) phase. If a platform's summon is not canceled, that platform will summon a voidsent add to the boss fight.
- At intervals, Bibliotaph will mark players with targets. If you are targeted, run to one side of the arena between platforms to bait the AOE he will place on you. This will pulse several times and inflict damage and Vulnerability on players.
