This page covers the elytra-related items currently grouped together in Slimefun's wiki mapping. It includes the crafting material that supports this branch and the two Slimefun elytra variants.
The Elytra Scale is a crafting component used in advanced elytra recipes and upgrades. Keep it if you plan to move into late-game travel gear.
The Infused Elytra is the magical progression option in this line. It is the elytra upgrade players usually craft when moving beyond vanilla flight into Slimefun gear.
The Soulbound Elytra belongs to the soulbound-themed gear branch. If you are already investing in soulbound gear, this is the matching elytra to look at.
