How hard is Ultima HM compared to other endgame content?

[kukurumei]

hard to believe because the dps check is pretty unforgiving. You have 10 minutes to kill it or you die and even with amazing dps, you'll only have about 2-3 minutes to spare

Not exactly. Garuda has a much higher dps check (2 minute to kill both sisters, 30 seconds or so to kill all plumes) One mistake, wipe there, it's over.

Ultima you can die multiple times and is given a recovery phase each time . If you have a bard, the MP from swift raise is nominal.

You can die multiple times in Ultima as long as not everyone is dying at the same time on the same phase.

The damage lost is nominal because the raise time is quick.

Only time it is not good to die is bits. Lasers have to die, as that will cascade. Ifrit rush, garuda push, erruption spam, bomb malfunction, all recoverable
