I suggest "light gravity" from the Inspired Quarter Mission Finale.
Be what levitation (level 2 spell) does for you.
It wont increase your jump, but you'll get higher and further by giving you feather fall, and lighter gravity to jump in.
Issues come with flight and levitation to do with enemy AI not being able to do much against a floating gun turret. So making light gravity means they cant stay up there indefinitely.
The other thing that levitation could do , is simply float the user just above the ground (much like mephits do), they're still able to be meleed with, And automatic feather fall as well . But are immune to knockdown, slipping on surfaces(ice or oil etc) , and can cross over water/lava/green mist surface as if it were solid.
(wraithform palemasters would also get this in that form)
Any thoughts?
