I think I came a little too overly prepared for these fights. I remember attempting these back during A8 progression and having the floor mopped with 6 portals, but that was before I knew how to manage my power charges and work with the build. The Breachlords were a joke because I guess I hit the damage threshold to keep them permafrozen lol

I don't think I need to bother uploading A9 Conquerors because they're all 1-2 shot 10 second fights. Not very riveting at this point.

My thought process for the encounters:

1. Don't roll any map mods with monster speed or AoE effect. Not being able to react or dodge at all is death.
2. Don't roll any map mods with reduced curse effect or reduced crit damage. I made the mistake once of having both vs the Breachlords and was wondering where my damage was.
3. Lingering effects bad. My priorities were to focus Minotaur and Hydra, Eradicator, Tul and Esh. Synthesis bosses were ??? as this was my first time fighting them lol

Big damage to kill them before the others spawn is pretty paramount. 2 bosses at a time is manageable, 3 is pushing it, but if you have all 4 with nasty map mods then it's pretty much game over.

Blasphemy Temporal Chains is definitely putting in some work here, though. Slower action speed, hinder, and big freeze/chills slows everything down and make things much easier.
