From what I've seen so far if there is no way to move around difficult terrain it prevents movement past that area, same goes for enemy threaten zones. But when both work together to prevent movement, movement is still allowed. I have a screen shot,
On that note, how do you add a screen shot directly to the body of text? The only way to insert images asks for a URL.
Zane, the reason those moves are legal is because you can freely move through squares occupied by allies. By moving through Aria, you can reach all those squares without running afoul of threatened or difficult squares.
It shouldn't be. Can you take a screenshot where that's happening? (I think if your ally is standing on difficult terrain in that case, you'd be blocked. Could that have been what you experienced?) Thanks!
I know i've experienced it before, but right after I posted that I noticed I could. I'll keep watching and see if I see it again.
In answer to your other question, you can only add images from an URL. I post mine to Imageshack and then link back.
