Very very nice midchapter, vote 9/10, well done!
For real, very very very nice changes, almost all of them, really really good job with the consistency!
Some concerns I have:
-Scourge Hook: Hangman's Trick seems fairly week, it should have an extra effect, or have a much bigger range.
-Spine Chill should keep the terror radius's strength, because it really helps in loops with tall walls with mindgames, so, please, don't remove that!
-Wiretap didn't need to be nerfed to 50% repair, it should be kept to 33%. Also allow the radius to be extended by Open Handed.
For the rest, very very very nice and well needed changed, really good job!
