If you attempt to send the bead through a narrow passage, such as through an arrow slit, you must “hit” the opening with a ranged touch attack, or else the bead strikes the barrier and detonates prematurely.

What is the touch AC of the narrow passage? This came up on Saturday night and my player insisted it would be a 10 (makes sense), and frankly it ended up not mattering, but it's not clear to me what the AC would actually be.

FWIW, I probably shouldn't have required the roll at all, but he was attempting to get the fireball through a double-door, a 10 foot wide hallway with 4 medium sized creatures blocking passage (2x2 in the middle of the hallway), and another double-door at the far end of the 20 foot hallway, from a position behind two other medium creatures. I thought there should be a chance he accidentally hits something in the hallway, albeit a very low one. He wasn't happy about it but he obliged.

I think you've wondered into the wrong forum. This is the card game forum, and I think you are looking for the RPG forum. Don't worry, it happens from time to time and I'm sure a moderator will be along shortly to move your post to where it belongs.

In the meantime, why not kick back and enjoy a nice game of Pathfinder Adventure Card Game? There are no confusing double doors or 20 foot hallways. Just Trapped Passages and Werecrocodiles.

Either way, I hope you get your question answered soon.

For a second, I started to wonder when Ranged Touch Attacks were added to PACG ...

There's no specific rule in the book that says "This is the fireball's touch AC for going through tiny holes."

However, if you look up Splash weapons under combat, I would logically use those rules. It's a magically aimed spell, and you pick a square. You don't roll a touch attack against a creature so it can't miss the square you are aiming at, so no need to roll percentage chance for the fireball to land at an adjacent square. The Touch ac for the small crack would be 5. If you hit, it continues on to where the intended destination was. If you miss, it impacts the wall besides the crack and detonates prematurely.

Assuming what the fireball hits and what your damage roll is, it's entirely possible for the fireball to miss, explode, and blow through the wall it impacts on, hitting stuff on the otherside anyways at no reduced damage.(Reflex save baring)

Ended up double posting this... Oops.
