If you are flying via magical flight and overrun another flying creature, what happens?
If the creature is using non-magical flight, did you collide with it, forcing a Fly check? I think so, but overrun doesnt exactly say "you crash into a creature and knock it over". If you fail your overrun manuver, does that still count as colliding with the creature and still force a Fly check?
If the creature is using magical flight, and you beat it's CMD by 5 or more, does anything happen? Overrun says "you knock the target prone". The prone condition says "the character is lying on the ground". So, if you overrun a flying target, is it immediately knocked out of the sky?
Interested to hear what other players and GMs think.
Ello, I don't have much experience with Flying Overruns, but I'll try to do my best.

Nope, if you fail an overrun attempt then you stop in the space directly in front of the target, no collision.

I'd say there would be a flight check involved, but I'm not sure to what degree. Originally, I thought it was a collision check, but a re-reading of Overrun yielded that you only "move through the target's square" if successful. I would say that in this case there is a good chance the two creatures do not collide, thus I'd treat it as if the target of the standard Overrun was "attacked while flying". This changes when beating the dc by 5 or more.

I don't think that the Prone condition would cause the target to plummet out of the sky - by itself. Usually only a Stun/Paralyze effect can do that. However I may consider this an aerial collision where the target now must face a "collision" Fly Check.
After all, getting knocked prone in the air doesn't really do much - as you can right yourself. Perhaps this would be considered "knocked severely off balance" and the creature would have to struggle mightily to maintain altitude/balance.
Additionally, I might consider this a "one-sided" collision in which only the recipient of the Overrun -> prone had to make the check. Or the initiator had to make a reduced Fly Check.
