General Discussion Thread

I was wondering if you could explain the mechanics behind boss monster's HP gauges. I've accepted the fact that a boss can have more HP than what Scan actually tells you. Someone earlier mentioned it acting similar to a boss having multiple "HP Bars". However, I've also experienced occasions where a boss has had an inconsistent amount of "HP Bars". It is slightly frustrating not knowing then general amount of HP a boss has, and how to plan my tactics accordingly regarding who to kill first.

Case in point, I've fought (and died, which is OK) Azala and Asmodeus numerous times now. Some of my battles have resulted in Asmodeus dying after 2 rounds of focused lighting attacks from my party. Other battles have seen Asmodeus taking the same amount of damage (or much, much more) without dying. There is no apparent recovery going on (Curaga, absorbing poison damage, etc.) that I can see, unless I am missing a huge mechanic. Any insight?
