I always read the rules as forbidding you from taking multiples of the same manoeuvre.

In this case, I'd actually feel jipped by the multifunction nature of your Thought Swiping Strike, as it means that, unlike if it were seperate manoeuvres, i can't have access to four of the best debuffs in the game in the same fight [they're all about as useful as each other, considering the commonness of immunities to stun and paralyse].

This is the first time when your scaling thing has seemed like a bad idea though...
