Stage 4 Prime Weapon's Effect On Sortie

Setup: RDM/DRK RUN/SCH BRD/NIN COR/DRG BST/DNC DRK/DRG. Ra'Kaznar Seal is highly recommended.

REMEMBER: Only those with a Stage 4 Prime weapon in their inventory can get Mesosiderite! It follows the same rules as the other -drites in this regard.

Pull quickly. RDM uses Saboteur to get the initial debuffs on (Frazzle III, Slow/Paralyze/Gravity II). Afterwards, start feeding Aminon TP. The idea is to get him into certain elemental states to get critical debuffs on:

Torrential Pain or Demonfire - BST uses Purulent Ooze to reduce his HP by 10% - Torrential Pain is easier to land under if the BST isn't max geared.

Blast of Reticence or Frozen Blood - RDM uses Saboteur and gets max duration Distract III on (drop Relic feet for Empyrean). If Blast of Reticence, the RUN or BRD can also attempt to land Armor Break/Shell Crusher. If Saboteur isn't up at this point, Random Deal it back.

Any Fetter-spawning TP move - the RUN, RDM, and DRK cast Tier I spells of the opposing element until red !! procs and the fetter is removed, unless you're stalling for time to get Distract or Ooze on.

After Distract and Purulent Ooze are both on, force Bane of Tartarus with elemental magic in minimal damage gear to get him back to dark/light-weak mode. Shortly after, he will use Incessant Void again - from this point on, never let him get another TP move off.

General Notes:
-Without Ra'Kaznar Seal, you will need a way to deal with several debuffs on the RUN, including Petrify from Ensepulcher and Doom from Impudence/Eternal Misery. You're also in much bigger trouble if he gets another TP move off later on.

-Incessant Void activates earrings which reduces magic and ranged damage taken by 90%, so melee damage is required. Hardmode AI change basically means you can never take these off. Dark and Light-based debuffs such as Absorbs are still effective, however.

-Aminon has similar Evasion to Albumen (1774 vs. Albumen's 1773), but without the benefit of Vorseals it's difficult to reach that amount of Accuracy. Either Distract III or SV Madrigals need to be on throughout the entire fight for damage to be reliable, but Distract will not land without either using Stymie or forcing Aminon to TP until he is in wind or ice mode.

-Aminon will always WS at 1000 TP regardless of HP%. Additionally, he gets 50 TP per basic attack even if the attack does 0, getting more if it does deal damage. Gravity kiting cannot avoid Aminon using TP, as he has Draw-in, but it can stop him gaining TP via attacking. Rely on Tactician's Roll for your TP.

-Enmity is generally not an issue in this fight unless the tank gets hit with Impudence or Eternal Misery, which reset hate. As long as the DRK uses High Jump, nobody else should be in any danger of capping hate.

-If Aminon uses a TP move, but it is NOT a fetter-spawning TP move, you can continue as normal as his resistances will not change. If it is a fetter TP move, you will need to force Bane of Tartarus for Absorb-TP to work again.

-While taking Aminon down like this, wings will flicker on and off occasionally with no real indication as to why. It doesn't seem to affect damage.

Job-specific Notes:

COR - Chaos/Tactician's Rolls. Unsure which one is faster to use Crooked on, but Chaos is safer. Use Savage Blade, and Quick Draws for TP/Dia enhancement. Jumps can also be used for TP as well if /DRG. Use Cutting Cards on the BRD after Soul Voice.

BRD - Clarion Call and Nitro after Bane is used - Honor/Madrigal/Madrigal/Minuet/Minuet. Put Sirvente and March on the RUN. Use Soul Voice after Distract wears off. Keep Dark Threnody II on - it lands without Nitro. Use Savage Blade when you get TP (Mordant Rime and Rudra's Storm both inflict Gravity, which may cause Aminon to build resistance).

RDM - Keep Dia III, Gravity II, Paralyze II, Poison II, and Frazzle III on at all times - save Saboteur for Gravity and Frazzle. Absorb-TP on cooldown. Keep Haste/Refresh on at least yourself, the DRK, and the RUN. Coordinate Impact usage with letting the DRK use Absorbs. I used Mercy Stroke, but another WS such as Black Halo may also work. After SV songs drop, use Saboteur/Stymie Distract III.

BST - TP Drainkiss on cooldown. Try to keep Box Step lv.5 up as much as possible. Our BST used Blitz - Calamity will likely also work. Use Sheep's Attack Bonus immediately after the first Bane, and reapply it if you ever get the chance to (Unleash is good for this).

DRK - Absorb-TP on cooldown. Other Absorbs land easily, so use as many as you want. Our DRK used Origin with a stage 4 Scythe, and is always by far the highest damage. Other WSes may or may not work. Keep up with High Jump usage to mitigate enmity.

RUN - Keep hate, and kite Aminon forever. Use Valiance on the RDM and DRK to help Absorb-TP cooldown. While Gravity II is on, stay out of his basic attack range at all times (but be sure to keep building hate). Use Gelus Rayke just before Stymie Distract to (maybe?) make it last longer.


Possible optimization / alternate strategy notes:

-If the BRD and COR both go /SMN and set up a Mew rotation, it may be possible for the BST to keep Corrosive Ooze's Defense Down on full-time. Alternatively, you could maybe swap the DRK for another DD - DRG may do well with Angon and Jumps.

-Keeping Aminon's TP somewhat high at times can give the RDM and DRK more TP to absorb speed up the fight, but be very careful you don't give him too much.

-BRD could potentially go /DNC to help keep up Box Step. Other support jobs may also work too, maybe even /GEO for Indi-Fury?

-Nothing in this strategy particularly requires RUN over PLD or another tank, you just need someone that can survive the initial attacks and then keep hate.

Things that need testing:

-How exactly is Mewing Lullaby nerfed on Aminon (if it is nerfed on the enraged version)? Is it similar to Gaol NM's, or worse?

-Does using Rudra's Storm actually cause Aminon to build resistance to Gravity? I know it does with other NMs, including Gaol. Just using Gravity II, the duration doesn't seem to change much even after repeated usage.

-Does Rayke actually help at all with landing debuffs or extending debuff duration? We always end up killing it before Stymie Distract wears off regardless.

-Is there ANY way to remove the Earrings without forcing Bane of Tartarus?
