There have been many reports on the boards about what you said regarding reach weapons. I wanted to get the real answer from you, not passed down through all those people. If a medium sized character is using a long spear does he threaten the second diagonal square from him?
Yes and no.
If he doesn't I would think he could still AoO anyone closing from the diagonal.
That's correct.
I just need a clarification.
The next FAQ will include:
Okay, so I can't reach 15 feet on the diagonal with my 10-foot reach weapon. Does that mean I don't get attacks of opportunity against foes who approach me on the diagonal?
If you're a Medium-sized character armed with a reach weapon you do not threaten a foe 2 diagonals (15 feet away), but if a foe moves up to attack you on the diagonal you still get an attack of opportunity against that foe before the foe gets adjacent to you (at some point the approaching foe had to be 10 feet away and threatened by you). Note, however, that if the foe moves adjacent to you with a 5-foot step, you do not get an attack of opportunity, even if the foe takes that step along a diagonal.
