This mod combined with the “I’m sorry but the Elytra is in another End City” + “Tectonic” + “Terralith” Mods makes it a decent substitute for the Elytra.

It has different tiers with more durability and it has different improves to enable it to be used in the Nether if it breaks or to be able to use it in storms preventing it from breaking if thunder hits you.

Additionally, it has a new mechanic that allows the player to be elevated if there is a source of fire below.
