The transmutation spell Glide includes this clause (highlighted in bold):
You take no damage from falls (as if from feather fall). In addition, you can move up to 5 feet in any horizontal direction for every 1 foot you fall, at a speed of 60 feet per round. You cannot use this spell to actually gain height, merely coast in other directions as you fall. If subjected to a strong wind or any other effect that causes you to rise you can take advantage of it in order to increase the distance you can glide. The spell ends as soon as your feet touch the ground regardless of its remaining duration. If the spell expires while you are still in the air you fall the remaining distance as normal.
Does that mean that if the transmutation spell Levitate is active on you at the same time then you may continually move horizontally even if you have no distance left to fall?
How exactly would this work? Do these two spells interact in any particular way?
Would it make any difference if another character was under the effect of Levitate or Levitate was cast on a heavy object and you were connected to either by a rope so that either "causes you to rise" when that object or character rises?
It seems that the spell Levitate is the only means that would "cause you to rise". Glide is otherwise still a very capable spell, it's not quite flying, but sure is "falling with style".
