I see - I just looked at the differences, and yes, I can see that.  Although from the extensive discussion on mirror images, I see the "adjacent" requirement in Pathfinder introduces some silliness, though I understand the need for something like it.<br/><br/>Asking as someone new to cleave, do I have to declare the cleave before beginning my swing (which makes sense), or after seeing the first blow hit (which could, ambiguously, be interpreted from the wording at d20pfsrd.org)?
