So, there's quite a bit of misunderstanding when it comes to siege engines.
The part I'm currently having issues with is how to represent them in a drawing of a castle.
So, first of all, a Ballista (large) takes up "a space 5 feet across", a light catapult (large) "takes up a space 10 feet across", and a heavy catapult (gargantuan) "takes up a space 15 feet across". For the light catapult, does that mean 5x10 feet? and for the heavy catapult, 5x15? Or are they squares, 10x10 and 15x15?
Then there's a slew of undefined spacing for other siege equipment (all of the ones in ultimate combat). How much space does a large, huge, or gargantuan siege engine take? Does the space include room for the creatures operating the device?
I haven't played in any AP's that involved siege engines. How did they represent them on the battle map or drawing?
