That's partially why even when I put them on my sheet, It basically amounted to 'give someone a dead arm or something for a bit' and nothing that'd win me a fight while also being hard to use and requiring actually fighting.

And yeah, I agree that just being able to easily land proper precision strikes to anatomical vulnerabilities mid-combat is definitely useful, but it lacks the sense of growth and progression that the powers seem like they're supposed to have in this game.
