Not sure if this is exists, or if I am just missing it somewhere, but one of the members of my group said there is a feat that allows you to stop an enemy's movement when you hit with a AoO. Anybody know what feat that is? FWIW, I have an Enlarged Polearm user, so my reach is pretty nasty and being able to stop movement would be pretty awesome. :)
As always, thanks in advance!
They probably mean Stand Still or possibly Pin Down.
And if you have Greater Trip, after you trip them you get an AoO, at +4 because they're prone...
That's why Pin Down is way better than Stand Still (but harder to get). Works when you don't get an AoO.
