Help! I have a group that is abusing the Astral Plane. Since time does not pass in the Astral Plane they have taken to plane shifting to the Astral Plane on a whims notice. If combat goes poorly they go, if they find a magic item that requires time spent (such as tomes) they go, if they go low on spells and need to replenish they go. Since time does not pass on the Astral plane the group can return at they same time (or at least close to it) they left. They use Teleport to get back to exact location and this is creating several issues with the adventure. The adventure is time constrained and this effectively gets around it. I don't mind the occaisonal jaunt but they plane shift almost daily and are able to avoid a lot of stuff with this tactic. Short of rewriting a lot of the adventure, planning an encounter during every travel to Astral Plan (which I think is unrealistic) there isn't much I can do. I am thinking of having the occaisonal encounter but there is nothing to stop them from Plane shifting somewhere else (execept dimensional anchor I guess but not everyone has that spell). Any ideas?
