Progress Report:

Done
The discipline has more than the minimum number of maneuvers/stances (4 stances with one of each 1st-3rd-5th or 6th-8th and 2 or more maneuvers of each level 1-6, 1 or more of 7th and 8th, and 1 9th level maneuver). It is theoretically "complete".
Maneuvers now allow you to do multi-round fear effect (but only if they bomb the Will save), jealously whittle away at every superiority your foe has over you, and avenge yourself for an attack/broken heart. Oh and gain 1 round fear immunity.

To Do
Change 8th level Stance.
More generally it feels lacking in Boosts/Counters (one Boost and one niche Counter) and could do with 1 or 2 more Boosts/Counters.
It also lacks a traditional "I hit something" maneuver at 7th level (instead having AoE fear effect and Etherealness Boost) which I feel may be a problem.

Ideas
Would "Make attack, deal +X damage where X is 1/2 the damage you have taken" be appropriate (if worded better) as a 7th level strike? Potentially that's quite weak, but it's also got potential to be stronger than Strike of Perfect Clarity... but only if you're really hurt. Maybe better would be "Make attack, deal +X damage where X is the damage you have taken in the last round".
