Well.. need to upgrade my software someday I s'pose
Anyways... what would be the rules for moving on or through those rock things, if say, for example, Khoros would get the mad idea to make an orkish running charge at that fireslinging Kobold 8, moving up a straight line to 'I12' or 'H11' once that pesky swordfighter goes down (damn those things are tough!)?
It'd be a lot easier to charge to G, H, or I 13. If you want to move through the rocks, you can make an athletics check to do so at half speed, but you can't charge through them (at least, not at heroic tier).
