So, in a few hours it'll be my first time DMing in ever (I'm not the usual DM for our group, there is more of a round-robin thing going on and sessions are quite irregular). Because I didn't want any misunderstandings to occur during play I distributed a document containing some houserules and clarification on some core rules which- in my assumption- had been misinterpreted in our past sessions.
Not everyone agreed with my interpretation, and I would like to see this cleared up before our session begins:
If a character (let's call him Alex) moves out of a square (using a move action, not a 5-foot step) threatened by someone wielding a reach weapon (let's call him Bob) in order to move next to Bob and to attack Bob, does Bob get an attack of opportunity or not?
It is my understanding that Bob does indeed get an attack of opportunity against Alex, whereas it is my players' understanding this would only be covered by Bob readying an attack action (presumably with the trigger "Alex moves into range")- which I presume to be an entirely separate mechanic and does not interact with Bob getting an Attack of Opportunity on Alex.
