Can a reach weapon attack and receive attacks of opportunity through a square occupied by an ally, and without penalty?
The situation was a pair of skeletons, one in a single-creature-wide choke point I was blocking, and another behind it with a glaive, when I provoked an attack of opportunity:
In my D&D 3.5e party I am essentially the tank, cruising around with the highest AC. So my party enters this dungeon and we stumble upon these two 5-foot wide and 10-foot tall stone doors. I roll a strength check to open them and succeed, only to see four skeletons rise from their caskets and charge at me. So I proceed to try and close the giant stone doors, which is a choke point preventing any skeletons except the one in front of me from attacking. I provoke an attack of opportunity from the skeleton in front of me, and apparently, another AoO from the skeleton behind that skeleton who has a glaive. The situation looked something like this:
I deflect the attack of opportunity from the skeleton in front of me, however the glaive skeleton crits me. I am knocked unconscious and the skeletons pour out of the room and completely destroy my companions. My only question is that since there is a skeleton in front of the glaive skeleton, can I still get hit by the glaive?
