Funny but I don’t think it fits the sub
I reviewed the spell, I was incorrect in assuming no portal was opened with a teleportation circle. In that case it should work out.
Glad you got a good group. My only real advice is stay consistent
Do you have a teleportation circle or a portal? A teleportation circle is like a star trek teleporter your velocity is matched with the destination on arrival no cannon.
If you have horizontal portal then sure you could drop a Boulder down such a shaft but I would be careful as this is open to exploit.

I wonder if we can make a 8 bit adder out of gate keeping
