We're having some trouble in our game regarding whether or not a rogue who is hidden (using the stealth skill) catches their opponents at range either flat footed or denies them their Dex bonus to AC (as is needed for a sneak attack).
I know there are various abilities that do allow for this such as:
* Attacker is invisible
* Target is blinded
But we can't find where, if it all, it says that a rogue who hides in the middle of combat is then able to sneak attack from range. The specific situation that brought this about was:
We are in combat, have been for several rounds now. We see a rogue run to a building and enter it through a 20 foot hole in the wall. After we defeat the melee combatants we pause and turn to the hole, ready to go after the rogue. Then our cleric gets shot, the arrow coming from out of the hole in the wall, taking sneak attack damage. I (Paladin, sword and board) raise my shield and advance towards the hole in the wall. I then get shot, taking sneak attack damage with the GM saying that as I was unaware of the exact location of the rogue, he was catching me flat footed.
What rules support/contradict this?
