[Snake]

Winged Serpent uses some sort of magic seal to maneuver your character while midair, so I disagree on this, because you could like, teamwork your way into an Air Shaft to move around while immobilized or something.

And I think the problems are only laid upon Gain Air and Burn Up on this, Air Shaft's Airborne should be a freebie way to make you fly around with Winged Serpent, or just straight up remove Immobilize.

Backflip is a bug. Heck, you can use it while Grappling people.
