(3.5) Attacks of Opportunity question

[j00callme]

Hi all, I was hoping one of you D&D gurus might be able to help me settle a dispute in our group. We had a situation were a pc was fighting some goblin dogs, I am the dm, and I had one of the dogs take a 5 foot step from one of the pc's threatened squares to another to move closer to a square that would put him in flanking position on the next round, I then made a melee attack on the pc, and I was told that while the 5 foot step did not provoke an AoO, the melee attack did. I made the argument that the dog's bite attack doesn't provoke an attack of opportunity either, they stated that since the taking an action after the 5 foot step, this causes the dog to lower his defenses and is subject to an AoO since the PhB states:
'Two kinds of actions can provoke attacks of opportunity: moving out of a threatened square AND performing an action within a threatened square.' and not using 'OR performing an action within a threatened square.'

So am I just reading the rules wrong or what?

[MesiDoomstalker]

No AoO. If the dog was trying to Trip, then yes AoO is available. Only actions listed as provoking AoO will provoke AoO.

[LTwerewolf]

No, it didn't provoke an AAO. A 5 foot step does not provoke, and a (full) attack does not provoke. There is no instance where you provoked one.

[BowStreetRunner]

The key here is that some actions provoke AoO and some do not. If you have access to the Rules Compendium, page 8 has a list of which actions do provoke. If not, then use the one on page 141 of the Player's Handbook.

You're player has commited an act of reading comprehension fail.

Just breakdown the sentence and you can see why he's wrong.

"Two types of actions can produce an attack of opportunity: moving out of a threatened square and performing an action within a threatened square."

It's saying that there are two kinds of actions then listing them.

Reading the "and" as associating "moving out of a threatened square" with "taking actions in a threatened square" changes the context, from two things that provoke to one combination of things that provoke, when the sentence already clearly setup the context.
