I keep forgetting that the olympics even existed.
Anyways, you misspelled LurkingShadow in the scope's name. It also still drives me nuts that you 'shamelessly copy' Ammorth's line segments' code as opposed to just using it for Glacial Wall. I'm pretty sure he updated it to be usable, even in your case here. Otherwise, everything looks good and in order. Thank you for making your spells easy to follow and with sensible looking code, it goes a long way to make reading over it smoother.
