It seems like whenever I will be farming and minding my own business, an enemy Furion's ult will come out of nowhere and hit me on the last bounce, taking a large chunk of my health.
When I play Furion, I know that I can cast it globally on any creep that I have vision of. Does it use this same idea to determine how it bounces across the map? That is, will it only hit enemy heroes/creeps if you have vision of them?
