Is this Oct Solo and Side Quest Events Summary Accurate?

Magonus

Did I get this right?

You need to complete (fully) Solos in Sept or you don't get one or both of the Symbiots in Oct
If you get the Oct Symbiots, you need to complete Antivenom Solos to earn Antibodies
The Antivenom Solos is to level up Antivenom who you may not have due to Sept solos or may not yet want to because the regular Level Up Event was not released
So you lvl him up, get Antibodies, the Antibodies unlock Cosmic Eclipse
Play Cosmic Eclipse to get Klyntar Katalysts
Use Klyntar Katalysts to rank up Summoned Symbiot (Steve??)
Use Summoned Symbiot in Cosmic Horror
...First run you'll just have to do one path and face the first boss.
...Second run you'll have to do 2 paths and then exit for the second boss.
...Third run is 3 paths and exit to boss.
...Final run requires all paths to get to final boss.

Did I get this right? Clear as mud?

No takers eh? Maybe there is a better summary out there? Shopping / To-Do checklist maybe? Thanks all.

That looks right

I don't know about the Cosmic Horror part, but the other thing sounds right. Except that you need to complete only one difficulty fully in September to unlock it
