Three characters have jumped/fallen into a 10' by 10' pit (depth 10', but not relevant). Two skeletons want to jump in with them. First one jumps down. The pit is now full. What happens when the second skeleton jumps into the pit?
The issue here is, of course, that the pit consists of 4 squares and 5 (let us say medium) characters would occupy 5 squares. Still, it is completely plausible for the skeleton to jump in, and completely unreasonable for it to be teleported up to the previous empty square it occupied due to invalid movement.
I am interested in rules as written (my present understanding is that "moving into illegal space" is the relevant rule here, but I would love to be wrong) and in reasonable house rules or interpretations.
In actual play we (the group) ruled that it is okay for the skeleton to jump down and try to land on someone sword first without any specific consequences; since it was about to be destroyed immediately with high probability, this was an easy choice to make. In the long run a solution more consistent with the other rules would be nice.
