I gave it a quick test. So far so good. Nice work. I first tested it a few times on the Moathouse frogs, with the longspear being grappled= everything works correctly: the close frogs are not attackable, only the frogs that are further than 5'. Once the grapple is broken, the reachman can then either 5' or move (which triggers AoOs) to allow for correct attack distance. In the image below: The northern reach (grappled) can only attack the highlighted frog. The active reach can not, unless he moves away. This image shows a safer approach: I was trying to think where enemies have reach weapons: Emridy Meadows skeletons and Moathouse Lareth fight guards are the only 2 that I can think of within the regular Temple range . I'll give those a few reruns soon. _______________________________________ Imho, Whirlwind has so many pre-req feats and it's not so powerful late game --- so I don't see this as a big issue, if it is the case.
