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.
