Is there anything that states what actions result in an opportunity attack, other than moving out of someone/thing's reach? And if so, does a successful attack stop any/all actions?
ie: Had a player attempt to deliver a Coup de Grace on a sleeping foe with another foe at his back. It was decided at the table (not my suggestion) that this action would cause an Opp. Attack. The enemy landed his attack and it was then decided this stopped the CdG action.
I kind of don't think that was handled right.
Does a successful Opp. Attack end your turn, or does it just halt your movement?
