I cast Blade Barrier in a wall in front of me. I then cast another Blade Barrier in a circle shape, so that part of the line intersects with part of the circle.
What happens at these points of intersection? Realistically I would assume 2 walls of blades to tear each other apart, but Pathfinder is mechanical, not realistic. Would a mob passing through this point of intersection take damage from both Barriers, or only one?
