I don't really have the time to read through the entire thread, so I'll give my opinions on the OP. If I don't mention something I agree.
Chapter 1:
Only issue I have is that wasn't Ironside's familiar. It was Pelegarde's. Ironside doesn't know Percival is alive until later in the story.
Chapter 8:
Percival's resistance justification should be changed. He was still knocked out, he just woke up quickly.
Isn't Nasiens just using his magic to give them poisons?
Chapter 12:
I fail to see how this is Reality Warping
Chapter 17:
Is that Fear Manip or Social Influencing? I know there's a difference but have some trouble with the difference.
Chapter 24:
IDK, that could just be him dispelling his illusion on the map. I'd be more comfortable with Summoning for that than Teleportation.
Chapter 25:
I think the implication here is that Anne is able to tell he's faking that he is losing.
Chapter 26:
Power manipulation isn't a thing to my knowledge? Isn't this just a further justification for his Poison Manipulation?
Chapter 28:
This is just Illusion Creation as revealed later.
Chapter 36:
Cernunoos isn't from Purgatory, but hell. I think that should mean The Demon Realm?
Chapter 38:
Doesn't Gowther have Immortality Type 1
Chapter 42:
King's justification is worded incorrectly. It should be (Taught
a spell to hide his and other people's magic to Lancelot)
Chapter 43:
Stat Negation isn't a power I'm familiar with. I think you mean Statistics Reduction.
What Nasiens did here was nullify the poison. On top of that Nasiens buffed himself with the Cerrunos drug.
Chapter 53:
Chion should also be given the ability to see Invisible things.
Chapter 69:
No, this is revealed to be a neurotoxin that messes with the sense of direction later.
