More Upgrade Template: Above the Sky (MUT: ATS) is an add-on mod for the mod More Upgrade Template (MUT).

Have you ever dreamed of breaking free from the limitations of ordinary elytra, giving each of your epic armor sets the ability to soar through the skies? MUT: ATS turns that dream into reality.

Core Features:

Armor Elytra Conversion: Use the brand-new "Elytra Upgrade Smithing Template" to upgrade most chestplates from MUT (Steel, Dragon, Blue Diamond... to vanilla Iron, Diamond, Netherite) into Elytra Chestplates.
Free Switching: Freely upgrade or downgrade your Elytra Chestplate through the Smithing Table (e.g. Iron Elytra ↔ Diamond Elytra ↔ Netherite Elytra).
Material Compatibility: Supports switching between different elytra variants, allowing you to change the elytra appearance on your chestplate.
Seamless Integration: Content is deeply integrated into MUT's upgrade system. You can use MUT materials (such as Advanced Steel Ingot, Blue Diamond Ingot) to further strengthen your Elytra Chestplates.

Give your legendary armor a pair of wings, and conquer even greater heights with your modpack!
