FFXIV M6S Adds OT POV (Toxic Friends Strat)

Raidplan: https://raidplan.io/plan/Pgj53K49w8LA...

Guide & timeline:

00:00 Wave 1

Pull the yan west and slight south. This avoids melee dps accidentally hitting the feather ray (manta) when it spawns with their aoes. Save the 1 min burst for wave 2. Pld can holy spirit the Gimme Cat to help.

00:37 Wave 2

Wait for ranged dps to hit the NW manta, then pull the yan over (if not dead) and use 1 min burst on the NW manta/yan help kill it. Notice how since the yan is dead here, the MT comes over to help kill the NW manta too.

01:00 Wave 3

Aggro the 2nd yan asap and pull slight north. As the party is killing the jabberwock, use your party mit to help with the raidwide the boss will soon cast. Pld can help on the jabberwock/mu with holy spirits.

01:38 Wave 4

Aggro the 3nd yan asap and pull W, then SW. Hug the west wall and be careful not to be clipped by the ranged dps dropping puddles or come close enough to squirrels (Mu) that the yans enrage. Stack the yans under the SW manta and use 1 min burst on them. Try to do as much dps to the SW manta as possible.

Once you see that the SE manta is dead, move to the far corner so that MT can come over and help kill the SW manta. Use ALL remaining mitigation in this phase.

02:57 Arrows & tankbuster

Once the last mu is dead you can come back to the boss so that the party can help kill the yans. Yans must die before the boss is able to start casting her raidwide.

Avoid the arrows and prepare for the tankbuster. If you used all mit on the yans you will need to ask for a gcd shield from the healer (adlo etc) to survive the tankbuster.

My suggested mitigation:
Wave 1 : sheltron only (just to avoid overcap gauge)
Wave 2 : sheltron only
Wave 3 : rampart since the bound healer cannot heal you.
Wave 4 : bulwark + sheltron when moving the yans. Sentinel followed by hallowed while party is killing the jabberwock. Sheltron again and reprisal after. Rampart if necessary (it should come up soon after all the other mits wear off)

Tips:
STACK YANS UNDER MANTAS when possible for aoe cleave damage and use 1 min burst on mantas. (This applies for MT too, should stack squirrels from wave 1-2 under NE manta and stack wave 3 squirrels under SE manta.)
Do not underestimate the damage from 2 yans. Each yan does 60k per autoattack with no mitigation. It is very easy to go from full hp to zero if you have no cd's and healers are distracted.
You can shield both raidwides in this phase by using your party mit on wave 3 and again immediately once it comes off cooldown.
Stuns and arms length do not work on yans but reprisal does.
Pld can turn off tank stance and send its ranged 1 min burst on the jabberwock in wave 4 if needed.
Pld's wings can be used as mitigation of last resort for the tb if you spent everything on yans (it gives guaranteed block if channeled).
