Unlimited creative flight with those 2 in inventory. Even when the Wings of Bat are recharging I have creative flight.
Same with the Launch enchant I can continuously use it.

wing charm = inf freefall
can you elaborate more.

NOTE: wtd prefers to "nerf" easy flight so these can be "balanced" with some more details on what you mean
