Terraria Wiki → Wings and How to Make Them
To craft a pair of wings and begin flying, you'll most likely need to defeat a Vyvarna, which appears after killing enough Harpies. It drops the main component—Essence of Air. Another requirement is that you've let the spirits of light, darkness, and rainbow into the world, i.e., smashed a demonic altar in the distortion . Crafting most wings requires a mithril anvil.
