pathfinder 1e: when do you get your attacks of opportunity renewed?
discuss. the rules are ambiguous on this.
some things refresh on the start of your turn (e.g. one spell per turn), some things refresh at the end (immediate and swift actions).
seems like refreshing them on the start or end of a creature's turn would be the most logical choice, then.
personally, i feel like refreshing them at the end of a creatures turn makes the most sense.
like immediate actions, AoOs may optionally be used when it is not your turn.
like immediate actions relationship with swift actions, then, if one uses up their AoOs out of turn they should be unable to use them when their turn comes up.
as a corner case, every creature should have their whole round of AoOs available at the start of combat. this way, something with Uncanny Dodge could use their AoOs before their turn, which is the intention of the special ability
