But it is not required to leave the threatened area and Zynna is leaving a threatened square only to enter another threatened square, there is even a picture in the player handbook about it.<br/><br/>About the troll not having perform an OA on the first turn, well maybe Melendrith just ignored that as we are not playing tactical battle mat here so it seems no OAs at all or at least no strict OA rules on threatened squares which is fine by me by the way ^^
