Moogle Ambuscade V1 Kupo!

Bozzetto Voyager Moogle:

Uses the following TP Moves:

Invite Over: Summons Bozzetto Steward, which has a short-ranged aura consisting of extremely potent Dia and elemental(?) DoTs
Washtub: AoE damage and stun
Mogsplosion: AoE damage with knockback
Contaminated Concoction: Disease
Somnic Shell: short-timed AoE sleep
Crystaline Flare: AoE light-based damage with flash and stun effects
Atra. Libations: conal gaze terror
Can use any of the SP moves available to the starter jobs (e.g. Chainspell, Perfect Dodge, Mighty Strikes, Benediction, Manafont); usage seems to be dependent on HP; number of uses available varies according to difficulty; will have a visible white aura

Bozzetto Steward:

has extremely potent Dia and elemental(?) DoT
does not move
will despawn over time (approx 1 minute)

Moogle:

Does not move on Normal and lower difficulty; will roam on Difficult and Very Difficult
Provides an aura that will counter-act the Voyager Moogle's aura but also gives amnesia; aura only activated when boss uses SP

Setups and Strategies: Very Difficult: Setup: SMN x3, GEO, THF/PLD, RDM

Strategy:

RDM gives Protect & Shell to the THF.
GEO uses Bolster and Entrusts Indi-Languor on THF, Indi-Frailty on themselves and will use Geo-Torpor once the boss moogle is in position.
SMN's have Ramuh's out and ready.
THF will run in, Perfect Dodge, Flash & Sentinel. Moogles will move, if they remain close to the boss moogle in the center, then the THF will need to bring the boss moogle away from the helpers.
RDM will Stymie Silence & Dia 3 then cast cures as needed.
SMN will Astral Flow/Astral Conduit right out the gate at 100% HP once the RDM has debuffed. This is the only real way you can kill him if he uses Benediction as his first 1-hour, and even then it's not guaranteed.
At 85% HP, THF will Larceny once the 1-hour animation goes off on the boss moogle unless it's Benediction. If it's Benediction, THF will need to Larceny if he uses Perfect Dodge, but you will most likely wipe unless your SMN's are stacked and can kill it before the aura becomes active and tick's twice. If the second 1-hour is Benediction, it's a wipe.

Alternate Strategy (not luck-based):

PLD, BRD/WHM, COR X2, RNG (or COR), WHM
Rolls: Hunter's and Monk's (for Subtle Blow), Samurai's and Chaos
Barsilencera and Auspice (along with Subtle Blow will help reduce the chances of Invite Over)
If the boss uses Invite Over, PLD should move a few steps away to avoid the spawn's aura.
Boss uses SP at 85%, 65%, 45%, 25%, and 10% HP. Reduce boss HP down to 88%, 68%, etc. and stop all damage. Then look for a nearby moogle. Wait until that moogle starts moving and then drop the boss HP down to the trigger level. The idea is to make it to the safety moogles right as they are about to stop. (If the boss has an SP aura up and the moogle starts moving, there is a good chance death). No damage during this waiting phase so as to avoid AoE damage and Invite Over. Spam Curaga IV and Curaga V (WHM needs Eber's Pantaloons +1) to ensure that no one dies if the boss happens to use an AoE spell or ability that everyone can still survive. Using any type of bind effect on the moogle can be helpful.
Save Rampart and Sacrosanctity for Chainspell; spam Finale to prevent the boss from self-curing.
If anyone dies, stop damage just before the next SP trigger level and wait out the weakness before forcing the SP move on the boss. Do NOT get up near a steward or when an aura is out -- wait until nearby stewards despawn and/or SP auras to drop.
This method is a sure way to win (unlike the SMN burn method) and does not require the use of SPs. Moreover, it is very easy on support jobs since only the PLD is ever in range of more dangerous moves such as Crys. Flare (high damage to non-tanks even with Shell V), Washtub and Atra. Lib. (stun/terrorize) followed by SP aura.


Difficult:

For D+ the regen moogles will roam around and not stay stationary.
Boss will 2-hour at 85%, 65%, 45%, 25%, and 10% hp.

It helps to DPS during the periods the boss has not used 2-hour and you do not have amnesia.

When boss uses 2-hour everyone should run to either regen moogle and stay close during the whole time amnesia is on.

It helps to slow down damage before a trigger point and pull boss close to a regen moogle, just depends how alert everyone in your party is.

Keep using dispel to remove pro/shell on boss, this keeps boss from curing himself.
The stewards will randomly spawn around the boss while you are DPSing.

Just move a bit away from them when that happens.

Silence during 2-hour phase helps. D and VD can easily be melee burned.
