AoO or not?

[Felon]

So an ogre walks on up to a druid who's casting Summon Nature's Ally without casting defensively. Does the druid provoke an AoO from the ogre and any other passerby that threatens?

When you begin a spell that takes 1 round or longer to cast, you must continue the concentration from the current round to just before your turn in the next round (at least). If you lose concentration before the casting is complete, you lose the spell.

I'd say yes.

SRD: “You only provoke attacks of opportunity when you begin casting a spell, even though you might continue casting for at least one full round. While casting a spell, you don’t threaten any squares around you.”

So, the Ogre would get an AoO only if it was in a square that threatened the Druid when they began casting, not if it arrives during the round’s worth of casting.


Edit: Any attack might still break the Druid’s concentration, as above.

Nevermind.

No, you only provoke AoO when you begin an action (movement is the exception).

I believe the answer is no. The druid would provoke an AoO during his own turn, when he began to cast, but he isn't in a constant state of provoking that grants anyone who comes into range later in the round an AoO.

If the ogre had been threatening the druid when the druid started, he'd get an AoO. If he comes up to the druid on his own turn afterward, he'll need to spend an attack of his own to hit the druid. No free AoO.

Now, if he does hit the druid, then he may be able to disrupt the spell.

Edit: Darn, too slow! At least all the replies above agree with mine, though.

Only the section on casting has this caveat. Nothing about, say, drinking potion says that you do not provoke an AoO throughout the quaffing. For example, if the ogre were to ready to move up to you when you're halfway through drinking a potion, he would get an AoO. But, not if you were casting a spell.

werk's doesn't.

Doesn't matter, that part is completely redundant, anyways. Only performing an action (and movement) can provoke an AoO, and you can only perform actions on your turn (ready and such obviously work different). It's just a clarification to an otherwise pretty common situation, which would certainly be questioned by a few people.

werk's doesn't.

Probably because I am wrong That's OK, I'm used to it.

I play devil's advocate a lot too...

Right, performing an action may provoke an AoO. But, you said "beginning" action is what provokes an AoO. That's incorrect except for spellcasting. For every other action that provokes an AoO, performing that action provokes an AoO throughout the duration of you performing it, not just beginning it. You have no basis for using the word "begin." If you do, however, please correct me. It is a rare, but important distinction.
