Tumult Curator

Setup (Initial - subjobs shown where notable) - PLD (popper) SCH/BLM GEO COR COR RUN/SAM | BLU/RUN BLU/RUN WHM GEO GEO BRD/BLM*
The sixth spot in the melee party swapped between the BRD, both CORs, and the RUN.  Other DDs can be effective if top geared: Samurai in particular can be greatly helpful on the Dvergr because of Warding Circle and Hamanoha.

Unfortunately, I don't think it's possible to do this with anything but a melee setup. Magic is ineffective or worse against Troll, Cerberus, Khimaira, and (most importantly) Dvergr, and RNGs probably can't output the damage required in time (roughly 2.4M all told with 12 people). Not to mention hate is the same as all other UNMs: damage is king. A BST strat might be able to do enough damage, but Dvergr Astral Flow, incessant Curse spam, nasty magic damage/status ailments and 300/tick Bio aura might be unsustainable. IDK, prove me wrong if you feel like it~

Buffs:

Geomancy: Indi-Vex/Attunement, Geo-Fury/Frailty for GEOs in melee pt, Indi-Attunement/Geo-Torpor for GEO in other pt.  We Entrusted Fend/Fade for Dvergr, you decide if that's worthwhile and what (if anything) to Entrust beforehand.  Vex and Attunement are by far the most important, and need to be kept up fulltime. Both GEOs in melee party MUST have Idris, the one in the other party can get away without it (but still very helpful).

Rolls: Hunter's, Magus, Samurai.  Fourth roll as whatever your DDs want, we chose Rogue's for the extra crit rate for CDC.

Songs: Honor March/Minuetx3 pre-Dvergr, Honor March/Madrigal/Madrigal/Minuet on Dvergr.  Honor March is mandatory.  Four songs is not, but helps enormously.  Fifth song during Clarion Call can be a Minuet, or anything else you think might help.

Both Blue Mages had Cocoon, Barrier Tusk, and Saline Coat set in addition to other normal spells.  I had Magic Barrier set in case of emergencies, though some other spell in that slot might be better.


The Fight:

-PLD spawns and supertanks everything.  BRD gives them Scherzo before they pop, no other buffs are really needed.  Use Aegis.
-SCH looks after the PLD until the Dvergr form.
-GEOs  be sure to tag every new enemy to ensure your bubbles are working on them!  A tier 1 nuke or meleeing it will suffice.

Phase I: Four Chariots (Level 119) - Order: Long-Armed Chariot -> Whatever
-Just kill the Long-Armed Chariot first to prevent Brainjack from going off, then kill the rest in any order.
-Scherzo on the PLD to prevent a one-shot from Discoid (10k needles, magic damage).

Phase II: ToAU Beastmen Kings (Level 125) - Order: Gurfurlur -> Gulool -> Medusa
-Gurfurlur is killed first to hopefully prevent Arcane Stomp from going off.  This TP move lets him heal from all magic damage, so switch to WSes that will NOT trigger Skillchains (we used Savage Blade) if it does get used.
-Gurfurlur has nasty conal moves, including Amnesia and heavy Knockback.  Pleiades Ray, used under 50%, can inflict things like Stun, Paralyze, Blind, Silence, Plague, etc. if not resisted (knockback -> Pleiades can suck...).

-Gulool Ja Ja's Miasma can inflict Slow and Plague if not resisted.  Mijin Gakure is used under 5% health, and can be deadly if allowed to use at 3% or higher; try to get it from 6% -> 1% instantly.

-Medusa's Eagle Eye Shot can one-shot a DD without Defense buffs up (Cocoon and Defending Ring are sufficient).  Has a lot of Petrify moves, mostly gaze and/or conal.

Phase III: Thu'ban, Sarama, Shedu (Level 135) - Order: Hydra -> Khimaira -> Cerberus
-Hydra starts at 50%, and regains 25% every time he grows a head back, like Tinnin and Thu'ban.  After all three heads are back, he will Polar Bulwark; it is possible to defeat him before this goes off with a strong enough skillchain.
-Hydra is dragged back to where it is to prevent Nerve Gas (30' range) from hitting the PLD.
-Tumult Lamps associated with Hydra (Dahaks) can use Nullsong if allowed to live too long, almost certainly killing the PLD. They despawn when Hydra does.

-Keep defense buffs up for Khimaira, and use Bio instead of Dia: Hundred Fists can be brutal if not proc'd.  Proc seems to be somewhat random.  RUN and /RUN use Tellus and Pflug on this to help avoid Stun effects.

-Fight Cerberus exactly like you fight UNM Sarama.  Unda/Vallation helps, but Vex/Attunement should block almost everything.
-The SCH curing the PLD supertank should be wary of Gates of Hades from Cerberus, it can kill them if they aren't careful.

Phase IV: Dvergr (Level 145):

-Dvergr uses:
    Spells: Curse, Impact, Sleepga II, Blindga, Dispelga, Tier V -ga spells, Tier VI Single nukes, Meteor. Most debuffs from spells will land even through Vex/Attunement, and nukes can one-shot a DD if not resisted.
    Uses normal Dvergr TP moves: Hellsnap, Hellclap, Thundris Shriek, Bilgestorm, Necropurge, Necrobane, and Cackle. Some have additional effects beyond the normal:
    Thundris Shriek: Respawns any Tumult Lamps that had been defeated.  Any Lamps that are awake when this is used level up.
    Hellclap: Copies Tumult Curator's enmity list to every Tumult Lamp (this is why Lullaby is vital).
    Bilgestorm: Gives Tumult Curator and all Tumult Lamps a ~250-300 damage/tick Bio aura (this is why SCH comes into the main party at start for Regen V/Embrava). The Defense Down effect from this move is ruinous and must be removed immediately, or Tumult Curator will hit for 700+ (easily fatal when cursed).  Bio aura has a 30' range.

-Tumult Lamps can use most of the things Tumult Curator does, but their spells are a tier lower. Dispel/Curse spam can kill your PLD before you're ready to fight if you're not careful.

-Fully rebuff after Dvergr spawns, in this order, Samurai/Rogue (or whatever other roll you want) COR -> Hunter/Magus COR -> SCH (Tabula Rasa Regen V/Embrava, prioritize duration on this!) -> BRD.  BRD uses full JAs, Horde Lullaby on all 6 lamps (make sure you sleep all 6, use harp if you need!), then comes back and sings.

-Accuracy requirement for Dvergr seems to be around 1600, if not a bit lower. Without songs/rolls, it can be a whiff fest.

-If 2xBLU like we did, they must keep the following up at all times: Lux x2 (Vallation/Pflug when up), Mighty Guard (alternating), Erratic Flutter, Saline Coat, Barrier Tusk, and Cocoon. Nat. Meditation is nice but not essential.  Cocoon especially is vital, it nearly cuts Tumult Curator's melee damage in half.  Bring Viles.  Unbridled Wisdom can be used for Harden Shell at any point if desired (preferably under 24%).

-Melee should have at least some DT locked for this.  I locked Defending Ring and Loricate Torque +1.  Not having any is asking to get one-shot at some point.

-SCH/BLM is for Elemental Seal Breakga (Manifestation) on the Tumult Lamps right before they wake, so the BRD can immediately resleep them.

-The GEOs in the melee party must survive!  Screw the Refresh pieces: if you're not recasting Geomancy, use DT- gear fulltime!  Bring Viles to keep your MP up!  (This also applies to basically anyone that isn't a DD, but especially for GEOs.)

-Everyone that isn't WHM or BLU (or maybe GEO if having MP issues) should have Vile Elixirs in their bazaar at 1g. Your WHM will need them.

-WHM has a heavy burden on them in this fight.  Melees can bring Holy Water or Panacea if they can't remove the debuffs fast enough.  Vex/Attunement should hopefully block most debuffs, but some (mostly Curse spam) will get through.   Don't hesitate to buy viles off of other players' bazaars!

-Consider Poison Potions or an equivalent if you're not a melee; Sleepga II almost never gets resisted, even with Bolster'd Idris Vex/Attunement. Bilgestorm Bio aura will wake you up immediately, of course, but that's not always up.

-Remove Bilgestorm's Defense Down effect immediately if it lands.  Do not hesitate to Panacea this.
-Those in the other party that don't need to be close to Tumult Curator should probably stand 30' away from everything to avoid Bilgestorm's Bio aura.

-At 74%, 49%, 24%, and 4%, he will use Astral Flow. The RUN must be in the melee party for this, and must One For All (magic phalanx equal to 20% of recipient's maximum HP at the time the buff lands: blocks this AF nicely) all 6 members in that party the moment it goes off.   Do not run if you're in the melee party, or you will probably die and/or get your WHM angry with you. Those not in the melee party should scatter and hope more than one avatar doesn't come after them.

-Each avatar summoned by Astral Flow targets a random person, walks to them, and uses their Astral Flow before disappearing. The AoE range is fairly short.  One For All will block most if not all of the damage to the melee party; other party will probably suffer some casualties.  This is fine, only the GEO suffers from dying and you can probably do without Torpor with all buffs up.

-One For All must be reset after every Astral Flow before the next one is triggered.  BRD needs their JAs reset before the Tumult Lamps wake up.  Don't hesitate to Wild Card if you have two Corsairs.  Hold damage if you need to, the RUN must be in the melee party before Astral Flow goes off or you die.

-The RUN should not use any JAs other than One For All if you're only getting Random Deal.  If you are getting Wild Card, use everything (don't forget Warding Circle).  Lux runes.

-Upon sleeping the Tumult Lamps a second time, redo the melee songs while JAs are still up.  Hold damage if you need to avoid triggering an Astral Flow.

-Don't hesitate to use Cleric's Drink and/or Megalixir from Ambuscade points if they're needed - where else are you going to use them?

-Enjoy your shiny new title, Rare Enemy vorseal, and (probably crappy) Tumult Curator's Coffer drop!  I got the staff...yay?  At least it beats the Master Trial's useless lockstyle drop...
