[PF1 Altered - Low Level Gestalt] Isekai Adventures

[thethird]

You can get as many Astral suits/Mindblades you can pay for (Those are Staged Features), you must track and buy stages for each suits and minblades separately.

I have many questions, sorry

Mind blade:
1) The only mind blade stage, would be the enhanced mind blade class feature. That improves at 3rd and every 3 levels from there. Correct?
2) If I take panoply of blades (from the psychic armory) can I have other mind blade modifications be part of the panoply? In particular I want the storied blade of the living legend to grab thousand blades of the champion and have a lot of different weapons telekinetically floating around me.

Astral Armor:
1) What are the stages proper?
1.a) Most astral armors (not all) get free customizations, at 1st, 2nd, 12th level. Are those stages?
1.b) Some customizations get increments to the armor at some levels, for example an integrator gets an improvement to natural armor at 1st, 5th, 10th, 15th, 20th level. Are those stages?
1.c) Aegis get customizations. Are those stages? If so what's the ratio? 1 customization point = one stage? Or as many customization points as you would get on a level = one stage
1.d) If an aegis gets several things from astral armor at the same level, are all those things one stage? Or are each a different stage? Practical example, an integrator gets at 1st level the mechanized body class feature (that replaces astral armor), that's one stage. It also gets 2 free customizations (is that an additional stage? 2 additional stages? 0 additional?), an increase to their natural armor (is that an additional stage? 0 additional?) and 3 customization points (are those stages?)
1.e) What's the effective aegis level (it limits the accessible customizations). Is it my level irregardless of how many stages do I spend?
