As the title states, it is possible to teleport thru the walls separating the outer two points from the one in the middle. E.g. by hugging the inner (mid) corner pointing to the outer point, guardians can use Judge’s Intervention to teleport to the outer wall (lion/dragon side) if you have an enemy targeted.
I get this is not intended as you are not teleported to the enemy player himself as it should be but instead just to the other side of the wall.
EDIT: The wall can be crossed to get from the outer to the inner in the same way, forgot about that part.
