Movement and Attacks of Opportunity, or, Things I Have Been Doing Wrong Forever

[Arturus Caeldhon]

So apparently..."Moving out of more than one square threatened by the same opponent in the same round doesn't count as more than one opportunity for that opponent."

from http://paizo.com/pathfinderRPG/prd/combat.html

That means I can walk around an opponent into a flanking position and only provoke a single AoO?

[Magda Luckbender]

Correct. This was a change from 3.5 to Pathfinder.

[blackbloodtroll]

No AoO chains.

Yeah, it's been that way since 3.5. Even in 3.0 it was kind of the same thing, except that, as I recall, characters were capped at one AoO per enemy regardless.

It wasn't a change from 3.5 to pathfinder. That is how it worked in 3.5 aswell.
Some people think that it is once per move-action per opponent, but that isn't true. Even if you double move around an opponent he still only gets one AoO because of movement. If you then start casting a spell, then the opponent gets another AoO (if he has any left).
