Q98: Is there anything, by RAW, that allows someone to make an attack of opportunity on an object that passes through a threatened tile?
Asking the wrong question. You need a rule to *allow* that. You can make AoO's on creatures, so the object would have to be somehow animated in order for you to make an AoO on it for passing through threatened squares.
... or, if the object is being carried, I guess you could use your AoO to sunder.
This is exactly what I want to do, actually. My party is about to cross a valley full of giants hurling giant objects at each other, and I'm trying to find ways to use my crazy powerful sunder abilities to break the boulders before they hit me. My rationale is that a moving object could still provoke reflexes, and as long as it uses up one an AoO it should still be balanced. I'm just trying to get some rules-backing before the game so that I can discuss it with my DM beforehand, and thus we can modify our plans as needed.
you mean while it's flying through the air? if so, I think you're out of luck.
I guess you could maybe ready an action for when the rock gets thrown ... but now you're in houserule territory.
As a DM, I
might rule it like this:
- must ready an action
- make sunder attempt, and count the rock as a 2-handed weapon .... just remember the size modifiers.
No AoO on the rock ... also remember that the rock is gonna have some crazy hit points ... if you don't break it, you take the damage and possibly break your weapon; if you break the rock, reflex save vs.
something or take 1/2 damage (save = no damage)
but that's just off the top of my head ...
