Thread: Upcoming SSR Kamihime/Eidolon discussion

The usefulness of Blind is preventing a triple attack from decimating a random party member (which if it's a healer or your Soul, could send you into an unrecoverable tailspin). With 3 attacks in a row, it's likely that at least one will miss. In Advent battles (except Ragnarok), you'll have some turns before the boss fight to charge the summon. For most players, surviving Ultimate is the primary goal. Raids are often long enough that the initial charge period won't be that long compared to the overall duration of the fight.

Behemoth, Phoenix, and Apocalypse are not interchangeable because a LV40 (or 55) and a LV100 eidolon don't have the same base stats. This is why Gatcha eidolon are typically useless for your active party.
