Also, coming back to this, there's a lot wrong with this.
The spell lasts for a maximum of four minutes before you have to cast it again. That makes it useless for scouting or searching unless you're somehow capable of doing everything in four or less minutes or if you're planning to chain cast, which is a bad idea. You also get a headstart on running away with this spell if you're in an open field, but you only have four or less minutes to do so. If you fly too high, you'll drop to your death or you'll have to chaincast. You can attempt to kite and strafe enemies if your own enemies don't have ranged abilities, which is good enough, but you're seriously overplaying how much utility four minutes max of flight time provide you. You're also forgetting that if you're caught off guard, you have to spend a round to cast, then spend a few rounds to get out of reach.
