Just a little mod that adds a few items to craft an Elytra.
• Aerite: The soul of the process. A rare overworld ore that spawns between y16 and y-64, with more spawning the lower you go. (will spawn lower if mods allow for it) Can be mined with an Iron Pickaxe. Used to craft the frames for the wings, and the neckpiece.
• Woven Phantom Membrane: Crafted with eight Phantom Membrane. Used to craft the wings and neckpiece. Wandering Traders occasionally sell them.
• Elytra Wing Frame: Crafted with Seven Aerite. Used to craft Elytra Wings.
• Elytra Wing: Crafted with one Elytra Wing Frame and four Woven Phantom Membranes.
• Elytra Neckpiece: Crafted with six Aerite and two Woven Phantom Membranes.
• Elytra Recipe: Can be crafted with two Elytra Wings, one Elytra Neckpiece and two String.
I literally made this mod in a few hours. If there are bugs, let me know. I'll fix them. Also feel free to use this in modpacks, I guess.
