Arian's Overland Flight

You gain a flying speed of 40 feet for the duration. When the spell ends, you float downwards at a speed of 60 feet per round for 1d6 rounds. If you reach the ground during this time you land safely, if not you fall the rest of the distance and take falling damage as normal (1d6 bludgeoning per 10 feet of falling) and land prone.

Flying with this spell requires no more effort than conscious thought. When using this spell for long-distance movement, you can move at double the normal speed of a fast pace (800 feet per minute instead of 400 feet) without penalty and do not need to make Constitution saves to avoid taking levels of exhaustion for travelling for longer than 8 hours.
