The Clyteum was once the imperial army's largest manufactory, supplying munitions and war machines to sustain Garlemald's relentless territorial expansion. Where its cavernous halls once rang with the clamor of industrial production, they now resound with the shrieks of countless voidsent who emerge from fissures without cease. Jullus and the Garlean community hasten to contain the threat, but will need all the help they can get to secure victory...
Eyes on Me: Party-wide magical damage. The first usage also spawns a dangerous AoE around the arena, compressing it into a square.
Petrifying Beam: The boss will walk to the north wall, receive a temporary Directional Disregard, and spawn a moving red conal AoE telegraph. As the cast bar fills, the boss will slowly turn its head to the left or right. Move to the opposite side to remain safe. The attack will lock in when the cast bar fills, inflicting petrification on anyone hit.
Motion Scanner: Your foe is scanning for moving targets! Spawns an unavoidable line AoE that will sweep across the arena. When within the AoE, players will be inflicted with Motion Tracker that will deal magical damage (Launch) and knock them into the air if they move or attack.
Penetrator Missile (no cast bar): Stack marker on a random player, dealing magical damage.
The boss will use Petrifying Beam again but combine with several circle AoE telegraphs (Surface Missile) before the cast resolves.
Anti-personnel Missile (no cast bar): Spread marker AoE on each player, dealing magical damage. Combined with Motion Scanner.
Ripples of Gloom: Party-wide magical damage. The first usage also spawns a dangerous AoE around the arena, compressing it into a smaller circle.
Mortifying Flesh: The boss will begin spinning, indicating a late-telegraphed line AoE in front of it. It will then become untargetable and roll around the arena outside, then use another late-telegraphed line AoE through the center of the arena, followed by a telegraphed radial knockback from the center (Bodyweight Exorcism). This can be prevented with knockback immune.
Basic Vomit: Faces one player and does a late-telegraphed frontal conal AoE.
Bodyweight Exorcism: Sequentially spawns four stack marker towers, each dealing physical damage.
Mortifying Flesh: Similar to before, but will dash twice through the arena center.
Evil Emission: Spread marker AoE on each player, dealing magical damage.
Profane Pressure: Stack marker AoE on the healer, dealing magical damage.
Rubbish Disposal: Party-wide magical damage. The first usage also spawns a dangerous AoE around the arena, compressing it into a smaller circle.
Void Dark: Faces one player and does a late-telegraphed frontal 180 degree AoE.
Scrap Meddle: Spawns several line AoE telegraphs that summon multiple small and one large scrap puppets.
Puppet Strings: The boss will take control of the large puppet, causing it to do a late-telegraphed conal AoE in front of where the puppet is facing.
Puppet Strings: The boss will take control of all small puppets, causing them to do late-telegraphed point-blank AoEs.
Gluttonous Wire: Stack marker AoE on the healer, dealing magical damage.
Scrap Meddle: Similar to before but now creates two large puppets in addition to multiple small puppets.
Puppet Pair: The boss takes control of all puppets, forming a pattern of both conal and point-blank AoEs.
String Up: Players must keep moving when the cast fills or they will be inflicted with Strung Up, causing them to temporarily attack their allies.
Shadow Play: Telegraphed magical AoE tankbuster.
Puppet Mastery: The boss takes control of all puppets and lifts them airborne. They will rotate around the arena until the cast bar fills, then use their respective attacks at their final position.
Wrathful Wire (no cast bar): Spread marker AoE on each player, dealing magical damage. Used after Puppet Mastery.
This dungeon returns to the pattern of the patch x.5 main scenario dungeon involving Garlemald, after the patch 6.5 dungeon the Lunar Subterrane broke it.
The dungeon name is pronounced "Clue-tea-um" (from Alisaie's voiced lines in Two Worlds Entwined).
