I trying to attempt making the normal trip( knockdown ) so it causes the AOO. I not overwriting the other knockdowns I just move them to improved trip and greater trip. I thinking maybe making the person take there weapons off and attacking to get the AOO or having a check so the hands are empty. Just some thoughts. I have FunkySwerve function for making an attack or I could use TouchAttackMelee. I know it just anoying me that knockdown (trip) did not have that AOO like disarm. Any thoughts? Oh I trying to do it without nwnx. Thanks all.
