OK, I had Sothe 2 spaces from the top left part of Ashera's Aura. Sothe had the skill Pass, so he could walk through the aur and Ashera. Just for kicks I, decided to walk through most of the aura. When the cursor arrow came out of the aura, it still let me zigzag the path, all the way to the end of his movement range. This made Sothe walk maybe 5 more squares than he should have been able to. Sometimes if you move to far though, the cursor arrow will change path and get rid of the zigzag. It's a kinda funny to watch the character run like that. It might work with other characters.
