I didn't take into any considerations for terrain. Yes, I really should have consider it, but I (my brain) didn't want to worry about dealing with it. Sorry.@Knightfall
Questions:
1. what is the movement penalty for the 'hilly' terrain
2. what is the movement penalty for the 'mountainous' terrain?
3. I forget what 3 was about....
No worries. I was just curious what would happen if I used firewall to force them through the mountainous areas. In the end, most of them go before me so it won’t really matterI didn't take into any considerations for terrain.

However, none of the hills, scrub hills, or scrub plains would count as difficult terrain. (I think.) The jagged mountainous areas do count as difficult terrain. The two undead that ran towards the PCs didn't start out in mountainous terrain.
So, unless the undead or the PCs enter the mountainous areas, there aren't any movement penalties.
EDIT: Sigh... I guess the scrublands should count as difficult terrain. But, I'd rather not worry about it.![]()
