So, talking with my DM today and another fellow player in our group, and we are slightly confused over the wording and intent of PG. Keep in mind, some of these questions are mine, and some seem might be obvious, but I'm just asking for clarity sake.
"Polearm gamble
Prereq: STR 15, WIS 15
Benefit: When a nonadjacent enemy *enters* a square adjacent to
you, you can make an opportunity attack with a polearm against the
enemy, but you grant combat advantage to that enemy until the end
of the enemy's turn."
So, the questions I have are as follows:
1. Does this override the normal OA rules for shifting, teleportation and what not? Would seem overpowered, but which ruling is the more specific ruling.
2. Does this take place when the person "enters" the square, or when they "leave" the square? Basically, is he adjacent to me when I make my OA, or is he still considered non-adjacent. OAs occur before the move takes place, but in this case, it reads as if the OA takes place after the move has taken place (Basically, OAs are Immediate Interrupts and PG reads as if it makes the OA an Immediate Reaction).
Just trying to get a clear understanding of the intent of the ability.
The DM's thoughts are basically as follows:
"General: Moving provokes an OA when leaving a square.
Specific: Shifting (a type of Movement) does not provoke an OA.
General: Reach weapons cannot make an OA at the extent of their reach, only when the target is adjacent.
Specific: Polearm Gambit allows a reach weapon to make an OA at the extent of its reach, if the target is moving to a square that is adjacent to the polearm wielder."
This makes sense, but we are still curious if this is the correct interpretation.
