Strategy

• Unlike other Omega Impossible raids, it's possible to simply focus the main boss down (Ayr) and ignore the adds.
• Depending on the overall damage of the raid, you may spend many turns under Terror Absolute's debuffs. Plan accordingly.
• Zel makes a good GravitySpecial attack max charge turn is extended
  and PetrifiedStops enemy's charge diamonds from filling.
  target due to having very annoying/deadly charge attacks.
• Keep an eye on Nil and Zel's Overdrive gauges as the fight progresses. While they are rarely targeted directly, Warlocks will often use the Hermit EX skill Choke to rapidly farm Honor by striking every head at once. A combination of this and Chain Bursts can push the auxiliary heads into Overdrive and even activate their 50% diamond fill.

Strategy

• Dimensional Cleave has gone from "Massive Overkill" to simply "One Hit Kill without mitigation". Going for the Arm first helps to prevent this in two ways: As you're killing the Arm to stop the Cleaves altogether, activating its Heat triggers clears diamonds. You get two clears this way and should be able to get a Break before it can refill after the second Heat.
• As with the other Impossible Omega raids, the fight calms down a bunch once the add is dead. Just don't carelessly auto into Resolute Reactor at the end.

Strategy

• Before your first attack, land as many debuffs as possible on Leviathan Omega. Create Water Barrier will not clear debuffs, giving you three minutes to beat on the Halo.
• A lot of this fight's actions are state-based triggers. This includes Tidefall, which is now a TPK move, so tread carefully during the Halo's overdrive.
• The Halo still has to be able to take actions to self-clear. If a ParalysisCan't attack
  manages to land on it, follow up with DEF DownDEF is lowered
  and get as much damage in as possible.
• Once the Halo is dead, Leviathan itself can be Dispelled of its buffs and is fairly straightforward.
• If the Halo is below 91%, the body can be focused down to finish the raid faster. However, the risk that it will cast Create Water Barrier when Leviathan Omega is dispelled will remain.

Strategy

Despite being one of the simpler Impossible fights, this version of Yggdrasil is still dangerous for high-level newcomers:

• Capping Attack Down and landing a powerful Blind on Yggdrasil herself are important for surviving, as her normal attack is very strong. Bringing a friend's 4★ Tiamat Omega is also an option.
• While technically not required to win, having both the circle and Yggdrasil hit the same target can quickly become lethal and a 5-turn skill seal is annoying so knock out the circle ASAP.
• Watch Ygg's buffs and what debuffs you get very carefully: If you get hit with DEF DownDEF is lowered
  or Earth DEF DownDEF is lowered for earth DMG
  while she has ATK UpATK is boosted
  and an attack gets through it can easily deal over 5000 damage minimum, and if nobody has multiattack debuffs she may swing twice.
• If you wish to fight this boss solo, consider Rose Crystal Axe to reduce Nether Veil damage.

Strategy

• Killing the middle Primal Bit is the key to this battle. Once the threat of Unknighted triggers is gone, you actually don't take much damage until the end.
• The best way to kill the bottom bit is through Chain Burst damage from unleashing Charge Attacks on the other enemies. It's not that important to kill this bit but the field effect can be annoying.
• Aegis Merge Divido is local, so you may dispel your own instance of the buff and keep attacking without worrying about someone surprising you with a new trigger. New triggers will still wipe all of her debuffs, however, so hold debuffs if you think someone is going to wipe them.
  • It is safe to debuff under 60%, as Aegis Merge Divido will no longer trigger when a new player attacks.
• Once Lumi gets under 25%, she'll start triple attacking for up to 4400 damage per hit. Wait for everyone to trigger this Merge and Attack debuffs to land or you risk a character being triple-attacked to death.
