Any advice on AQ7? I cleared the first run on Thunder using an elixir, and then cleared without 2nd time through, but there's definitely STUFF happening that I don't really understand.

Stage 1 - top hits very hard. Bottom alternates debuffing my team and def buffing the monsters. Middle ougi is a heal (I target her last)
I haven't yet let stage 2 reach ougi (think that's the accepted term?) but - does it do anything scary?

Stage 3 - Really not sure what is going on here.

* When I don't use an ability, seems to trigger a target-all blast, dealing 2k -ish damage.
* Something is causing the boss to not attack occasionally. Not sure what.
* Something is causing the boss to add ougi-blobs, e.g. instead of firing ougi every 3rd, it goes to every 4th or 5th. Not sure what.
* Enemy ougi is usually 5 (I think?) attacks around 8k (excluding damage reduction). Could be more, could be less. Although it also sometimes does a target all for around 4k, not sure what decides between them.

If anybody is collecting a set of details for the different AQ7 stages, it'd be useful. Happy to contribute, check & confirm stuff, but at the moment I'm seeing a lot of stuff happen but not able to identify the causes.
