“Your foray into the caverns beneath Castrum Occidens has led you to an unexpected revelation: the incomplete form of Bahamut, harbinger of the Calamity, slumbers deep within earth. Though seemingly a prisoner, the elder primal is gradually being regenerated by the massive, Ragnarok-class internment hulks that surround the unmoving entity. Alisaie reasons that if Bahamut's full restoration is to be prevented, then all three coils sustaining and repairing the dreadful being must be deactivated. Filled with new determination, you assemble a group of courageous comrades and set your sights on the fragment of Dalamud found int he North Shroud.

Enemies
Bosses
Phases 1 and 2:
Bloody Caress is a frontal, conal AoE attack that applies a 
Vulnerability Up debuff to the tank. Rest of the party should stand behind the boss to avoid the ability. Rafflesia will use the ability once every 15 to 30 seconds in the first two phases. Tank Swap should occur every 2 - 3 stacks of the debuff.
Briary Growth is an ability that spawns 3 Dark Matter Bulbs at randomly selected preset locations. After some time the bulbs will sprout briars that deal damage and slow all players on top of it. The briar coverage will spread over time until it covers a substantial area of the boss room. By tanking the boss in the center of the room, players can avoid all the Briary Growth at the outer edge. If a Dark Matter Bulb spawns in the center of the boss room, kill it quickly.
Thorn Whip is an ability that tethers to different party members with visible lines. Players tethered together need to move away from each other to break the link or take about 300 to 500 damage per second. These tethers will only break by stretching them longer than their initial size; two players already at opposite ends of the platform becoming tethered will be unable to break the tether at all. As the battle progress an increasing number of people will be tethered. At the start of the fight, about 2 players are tethered, but at the end, up to 6 will be affected.
Floral Trap is an ability that marks a random player with a yellow sign then sucks all players near that player to Rafflesia, within melee range. Immediately after Floral Trap, the boss will cast Devour. Players standing on the vine areas of Briary Growth will not be pulled to the boss. The marked player should remain behind the boss while rest of the party should move in front of it temporarily. Players in front should be unaffected by the pulling this way. Rafflesia will use the Floral Trap after second Thorn Whip.
Devour is an ability used immediately after Floral Trap. It absorbs all players within the boss' melee range. The boss gains a permanent damage buff for every devoured player and removes the Honey debuff from Viscid Emission. Rafflesia will use Spit immediately after.
Spit is an ability used after Devour, it releases the players absorbed by Devour and deals about 2000 damage to all players in party.
Blighted Bouquet is an ability used at 70% HP, when transitioned from phase 1 to 2. This ability deal high damage to any player moving, attacking or using any abilities when it finishes casting; enough to kill most players that aren't tanks.
Viscid Emission is an ability used in phase 2. This ability places a Honey debuff on a single player. Dark Matter Hornets will spawn and attack the player with the debuff regardless of aggression; it cannot be taunted away. The player with the debuff needs to be Devoured or adds will continuously spawn and attack the player in Phase 3 without a means to remove the debuff. If the person with the debuff dies, Rafflesia will use Viscid Emission on another player, each time Viscid Emission is cast, another Dark Matter Hornet will spawn. If the add is not killed after a certain amount of time, it will use Sharp Sting, instantly killing the target.
Phase 3:
Leafstorm is used at the start of phase 3 and every two minutes afterwards. It deals about 2000 damage to all players in party and spawns three Dark Matter Slugs.
Dark Matter Slugs are three enemies that spawn immediately after Leafstorm, each having ~6000 health. They should be controlled by your off-tank and/or killed by caster Limit Break. At 50% health, Dark Matter Slugs will move to the nearest Acidic Honey and attempt to devour all Honey in range. If successful, they will fully heal, gain a significant damage and health buff, and periodically cast Acid Ooze.
Acid Rain is an ability used by Rafflesia shortly after the spawn of the Dark Matter Slugs. Acid Rain creates three circular AoE markers below randomly selected players. At the center of these indicators, 3 enemies named Acidic Honey will spawn.
Acidic Honey are slime enemies with ~50,000 health that will afflict the raid with a stacking debuff called Potent Acid. Additionally, if attacked, Acidic Honey enemies will counter-attack with "Acid Spray" dealing ~900 damage to the attacker. Due to the high health and high counter-attack damage, it is not recommended to kill Acidic Honey enemies directly. Players will need to be cautious not to use AoE attacks near Acidic Honeys.
Potent Acid is a stacking debuff given every 10 seconds while any Acidic Honey is still on the field. Regardless of how many are alive, only one stack of Potent Acid will be added per cast, expiring once all Acidic Honeys are gone. "Acid Cloud" damage is taken with every stack added, starting at <100 damage with 1 stack, increasing up to ~700 damage at 7 stacks. Every stack after 7 will double the damage. By 10 stacks, the raid will most likely wipe. This means players have 100 seconds to either clear all the Acidic Honey or kill Rafflesia.
Acid Ooze is a raid-wide AoE attack by Dark Matter Slugs cast every 15 seconds after having devoured Acidic Honey. Acid Ooze will do ~2500 damage to the entire raid per Acidic Honey eaten; if one Dark Matter Slug were to eat two Acidic Honeys, Acid Ooze would deal ~5000 damage instead. Regardless of whether one slug eats all three honey, or if each slug eats one, three honey's worth of Acid Ooze simultaneously is enough to wipe the raid instantly.
Swarm adds 4 stacks of the Swarm debuff for 6 seconds on the main tank. When the debuff timer hits 0, the tank will be hit for ~1000 damage per stack for a total of roughly 4000 damage.
Rotten Stench is a Line Stack marker used during Thorn Whip indicated by a blue circle above one player's head. Rafflesia fires a large beam at the marked player, splitting damage between all the players hit. When players are breaking Thorn Whip, they should move towards or away from the boss in a line to more easily absorb the incoming attack.
Strategy
Phase 1: 100% to 70% Players should tank Rafflesia in the center of the boss room with the tank in front of the boss while rest of the party behind it. Players should tank swap after 2 to 3 stacks of Bloody Caress debuffs. To avoid Thorn Whip tethers from being too difficult to break, players should stand relatively close together until tethered. Dark Matter bulbs that spawn in the center should be killed immediately, while ones on the edges can be ignored. The tank should reposition between Bloody Caresses to avoid standing in Briars growing around the edges of the arena.
- Rotation: Thorn Whip -> Briary Growth -> Thorn Whip -> Floral Trap -> Devour -> Spit -> Repeat
Phase 2: 70% to 40%
Phase 2 starts off with a Blighted Bouquet. During the cast, players need to stop moving, using abilities or attacking. All the players who are performing actions at the end of the cast will take high damage, potentially dying. When the boss uses Viscid Emission, kill Dark Matter Hornets immediately. The individual with the Honey debuff needs to be Devoured by the boss before the phase is over.
- Rotation: Briary Growth -> Thorn Whip -> Floral Trap -> Devour -> Spit -> Honey -> Thorn Whip -> Blighted Bouquet -> Briary Growth -> Thorn Whip -> Floral Trap -> Devour -> Spit -> Thorn Whip -> Blighted Bouquet -> Repeat
Phase 3: 40% to 0%
When transitioning from Phase 2 to 3, Rafflesia uses Leafstorm. The ability deals about 2,000 damage to everyone in the party. The boss will no longer use some of its abilities such as Blighted Bouquet, Bloody Caress, Briary Growth, Floral Trap, Devour, and Spit. The boss will no longer add vulnerability stacks to the tank, instead, a tank swap should occur after Swarm is cast, which will do about 4000 damage to the tank on a delay. After Leafstorm, 3 Dark Matter Slugs will spawn; ensure that these are picked up by the off-tank. Acid Rain will be cast soon after, spawning Acidic Honey underneath three randomly selected players. From here, there are multiple methods to complete the fight.
- The safest strategy is to kill the Dark Matter Slugs before they have a chance to eat any honey, potentially using an AoE Limit Break to aid in this. The Dark Matter Slugs do not have a large amount of health, so they die very fast. The raid will then have ~100 seconds to kill Rafflesia before the Potent Acid stack reaches 10 and wipes the raid, but this is easily done even at minimum item level.
- A similar alternative strategy is to have the off-tank grab the attention of the Dark Matter Slugs but NOT kill them, instead focusing purely on Rafflesia. While it requires much more healing, it removes the risk of not killing a Dark Matter Slug in time if the DPS are struggling with coordination.
- A common, but risky, strategy is to intentionally stack in one spot prior to acid rain to keep the Acidic Honey together before being eaten by a single Dark Matter Slug. This "Super Slug" replaces the 100 second death timer from Potent Acid with a 15 second death timer from Acid Ooze. A Melee Limit Break and full focus from all DPS is required to kill this Super Slug in time. Successfully killing this Slug, however, nearly guarantees an easy kill on Rafflesia. It is recommended for the off-tank to use an invulnerability here, as the Super Slug deals extreme amounts of damage with every attack.
- The much slower, but intended strategy is to have the entire raid split around the room before acid rain, trying to ensure that Acidic Honeys do not spawn near each other. Carefully damage one slug to 50%, let it eat one single Acidic Honey, and quickly kill it afterwards. Repeat individually for the remaining two slugs.
Players should also watch out for Rotten Stench. Ensure a majority of the raid stays directly behind the boss, moving directly forwards or backwards when tethered instead of to the side to ensure that the damage from Rotten Stench is split safely across the raid.
- Leafstorm -> Acid Rain -> Thorn Whip -> Swarm -> Thorn Whip -> Rotten Stench -> Swarm -> Thorn Whip -> Swarm -> Thorn Whip -> Rotten Stench -> Repeat
Be warned that Rafflesia will spawn another group of Dark Matter Slugs and Acidic Honey two minutes after the prior set if not killed fast enough.

Cutscene
Alisaie: How strange. Why could we not see all this before? Alisaie: I suppose it is only to be expected that corrupted crystals should accompany a disturbance of this magnitude. After all, the fragment likely pierced the ground to a depth of many hundreds of yalms. Alisaie: The swirling aether leaking from the wound must warp the very air, creating a veil that hides these formations from view. Alisaie: Well, it is not as if we expected this to be a straightforward task. Let's tread carefully, shall we, [Forename]? Alisaie: 'Tis imperative that we win through to the depths of this structure, and disable the mechanism that powers Bahamut's regeneration. Of course, if we should chance to encounter my grandfather upon the way...I shall not let him go again─not while there is hope that he may yet be saved. Alisaie: ...But mayhap we should put such thoughts from our minds until after we have successfully gained entrance to the place. That opening up ahead appears a suitable point of ingress.
