AS&SH is a bit too weird and complex for me (despite having backed the original release) but I love how it oozes flavor.
In particular, when rolling a random encounter with a lich in the wilderness, there is a high chance it will simply ignore PCs as it trudges along, unless they directly mess with it. It's such a powerful, scary thing that it does not even register living mortals as worth its time.

I think that's a lesson we can all learn from.

What are some other interesting ways you've seen for handling "OP" wilderness encounters - ie ones you can't actually outrun - without it being a slower, more painful "rocks fall, everyone dies" situation?
