What's the Bestiary inside of Electronic Brain mission?

[Saner]

are they mainly Casts or SEED forms? any new skins/enemy types in there?

I would presume they are dark type anyway. maybe.

is it 3 blocks then the boss?

or 5 blocks like the mission before it?

The rare enemy that doesn't have an english name yet is the Delsaber (it will probably have a messed up translation and be called something else.)

As for blocks.. dunno, I didn't play it offline.
