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:
-Per Wiki, BCNM Exit Points Should Land @ The Protocrystal

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