these wings loose durability as you fly, and can’t be destroyed from flying, but become unusable until repaired with a second elytra or with leather using an anvil, they require at least a 4 block high jump to activate, and respond sort of how a glider should, I tried it out on the snapshot, its not like creative flying, but from a maximum block height, they make castle walls useless, but can also be used to land safely from high builds as you don’t take damage so long as you don’t fall from to steep an angle or so long as you don’t stall. hope this was useful
