6.4.1 Following

You cannot follow anything but a player in Imperian because of the fundamental
nature of player movement. We do not actually like the idea of automatically
following something else, as we feel it is a little bit silly. Mobiles move
relatively slowly, and thus it's reasonable for you to simply move when and
where they move. Players, on the other hand, can move far too fast for you to
follow them that way, which is why one can automatically follow players, but
not mobiles.

CONFIG PATHFINDING GROUP <on/off>
You can flag yourself to not move when other people in your party following you are unable to move.
