Wanted to make a thread for tips regarding Mireu since I see some issues occur each time the server fights it. If you have any additional tips, feel free to add them.
Gathering people
-If you see the unity message or spawn Mireu yourself, alert people via ls, shout/yell, unity in intervals, and on server discords if they're cool about it, more people leads to the AoE limit being reached faster and people may want to get there early to not deal with Mireu not loading in
Addressing Lag
-Setting everything in config>effects to on will help with fps, especially when spikes are up, just make sure to change it afterwards or else you won't be able to see staggers in abyssea/sortie etc.
-I've heard different testimonies, but if Mireu isn't loading due to excessive players, you can go out of the arena behind Mireu and slowly walk forward for it to load. In Reisenjima, since the arena is small, people say you move away from mireu where you spwan and walk forward instead.
Debuffs
-RDMs can land Distract III for 10+ minutes with Sab+Stymie. I usually wait until there's enough people present and watch its hp decrease much faster with trusts being able to hit it. Cast a distract without stymie first to see if someone already applied it and check every 10/15 minutes to see if it wore off to keep it applied
-In addition to distract, RDMs can also land silence without much issue. However, duration decreases as the fight goes on, so I usually wait for the first chainspell with enough people present/while taking heavy AoE damage
-Mireu also gains dread spikes during Chainspell, so THFs can use larceny to remove both
-None of the DNC trusts apply box step, so DNCs and /dncs can help keep it applied
-BSTs can land corrosive ooze to help everyone, especially whoever has hate to take less damage
-Geomancy debuffs are nerfed a good amount
Buffs
-Because of all the trusts, some buffs are difficult to keep up, brds really only have honor march, cors have sam roll etc.
-If you are unable to see Mireu or joining in late, consider focusing on healing/buffing. Casting accession heals/buffs on your trusts will spread it across parties, giving out ~60 TR RegenVs/Embravas on sch or Cure4skins on whm is kinda nuts
Trusts
-A critical mass of Selh'teus helps a lot with healing and damage
-Since many players will already use brd/cor trusts, other trusts can be used instead to give more AoE buffs such as Shikaree Z for Ancient circle, Excenmille (S) for Stag's Call, DNCs for steps, Iroha II/Arciela I for more AoE healing
-For DNC trusts, Mayakov applies lv10 Feather, Uka applies lv5 quickstep, Mumor applies lv5 Stutter, all 3 give haste samba if on WHM,RDM,SCH,PLD
-Keep resummoning trusts especially at low hp to be able to soak its attacks. I think Mireu is also subject to the same limitations we are with AoEs only able to hit ~60 targets simultaneously.
Equipment
-If you can afford the inventory space, don't forget Zurim's cheap DI gear to boost damage/survivability if needed. The Feet slot is 50 WSD and those that can wear the shield get 30WSD 40MDT2
-Because of dread spikes, avoid x2/x3 dmg weapons
-Naegling is a good option because of dread spikes and all the buffs flying around makes its secondary WS atk buff potent
