Wow, this spell is a lot of fun. At one point, the enemy archmage and I swung each other from one end of the map to the other.
Unfortunately for me, hashtables are still gibberish, so as far as learning from this spell, I'm still trying to figure it out.
Regardless, it works, and is amazing. I haven't tried importing it into a bigger map yet to see how it would deal with multiple units fighting all over the map, but if two archmages can orbit each other, it should be fine in low doses.
