For now, it's just a forge mod that adds a custom elytra curios slot to the Elytra Slot mod, freeing up the back slot for a backpack or other uses. In the future I may add more features, like maybe some enchantments specific to the elytra, but for now it's just the custom curios slot.

This means that with this compat mod you will get one back slot and one elytra slot from the start. Changes to this can be made in the curios serverconfig file found the world save folder.

REQUIRED MODS:

Curios API
Elytra Slot
Caelus API


==========================
Optional Recommended Mods:

Elytra Utilities
Elytra Physics
