Accidentally Ending Movement in an Illegal Space said:Sometimes a character ends its movement while moving through a space where it’s not allowed to stop. When that happens, put your miniature in the last legal position you occupied, or the closest legal position, if there’s a legal position that’s closer.
Unless he stands up with a DC 35 tumble check and takes a 5ft-step, thus causing no AoO.irdeggman said:I like the FAQ ruling - but standing up also generates an AoO so the prone figure will end up generating 2 AoO to stand up and move out of the square.
