Flying Enchantment

The flying enchantment is an enchantment that only works on elytras. It lets you fly through the sky withour rockets or high towers. Lets take level 1 as an example: You want to fly up so you activate the elytra and instead or going downwards you fly up 2 blocks per second. Great right? Yeah, until the elytra breaks. The enchatment decreases the durability of elytras 2x faster than normal. (if elytra is used) The enchantment is compatible with mending and unbreaking. Level 2 would be (on my opinion the best) 3 blocks per second and level 3 would be 4 blocks per second. You basically fly 3 minutes and 45 seconds until it breaks. The normal breaking time without unbreaking or mending is 7 minutes 11 seconds. Villagers can deal you the enchantment but its only available at level 2 or 3 of villager trading. Piglins can also drop the book when trading. Im not a math expert but i think that a chance of 2,3% that the piglin drops a level 1 book is low. Level 2 books would be 1,8% and level 3 0,9%. I really hope you like it because i spent some time thinking about somethings.
