Just wanted to help anyone fighting the Eye of Leviathan. With a good strike force team you probably won't have too many problems but if faced with a hard time during the battle with the actual eye, here is a somewhat useful piece of information. The eye has a blind spot right above it at the top of the cave. If you have flight and ranged attacks you can kill it from this blind spot. It make take a minute to get in the precise position but it can be done. Just dropping a thread for someone who may need it. Happy hunting.
