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.
