I'll just leave it at this and tap out.You don't seem to understand how the rules work properly.
At my table you would only be able to cast up to 5th level spells, regardless of slots or points.
At my table casting many of the spells in your build would render you no longer "stealthed". Enemies would know both that an enemy was around and where you were when you cast the spell.
At my table no build would ever allow a character to "win" D&D regardless of how things were worded or interpreted, much like the bag of rats from 5e.
I challenge you to revisit your own interpretations on the grey areas of this build and acknowledge that the fundamental power of it lies in your definitions of those portions of your character.
