ASA-4 Sugar Coated Directive

Implements the 6 primal avatar fights for A Shantotto Ascension 4

In this fight, the avatars have special behavior where they start unkillable and can't be defeated until they've used their Astral Flow at least 5 times, triggered at a specific hp threshold

You must complete at least 3 of these to advance the mission.

The amount of gil rewarded varies with the number compeleted.

Thanks to @TeoTwawki for helping me with Avatar IDs

TODO?:
-Confirm if glitches in the entry cutscene related to the avatar are my fault or more of the existing entity update issues with them. Note: as in the open issue for Leviathan, he's totally hosed but im seeing pretty much all the avatars occasionally moving weird during the battle, and glitched during the CS.

Despite this, the mission is totally playable and none of this hinders progress.
