Dimension Breach After a Long Time

I had left it untouched for a while because I couldn't climb past the Omnic Emperor, but I finally found an easy strategy. I'll write down the details for reference. - Path of the Undying (with/without Ethereal, Eidolons) - Blade of the Ephemeral (with/without Ethereal, Eidolons) ← Maybe easy with 2 Eidolons... - Curene (with Ethereal, 2 Eidolons) - Hian-si (without Ethereal, 0 Eidolons / borrowed) Gathering Destruction/Memory to boost HP (e.g., Instant Death Dodge, HP Recovery) Make sure to have both Lord of Nightmares and Eternal Invoker (Especially, it's desirable to have Eternal Invoker by the second boss)
