Do you need to roll break away when on a higher elevation than the opponent through a ladder or stairs?

I would guess no, since it isn't considered adjacency but only for attacking?

You would guess correctly. The characters are only considered adjacent for the purposes of making close combat attacks, nothing else. So movement is unaffected.

Thanks a bunch.

This also works for stairs. I only mention this because there used to be different rules for stairs and ladders, but now they are the same.
