Cosmic's Adventure Reimagined

This update adds new uses for shulkers, re-themeing shulker shells as shulker pearls, which can be used to brew haste and levitation potions (haste = awkward + shulker pearl, leviation = harming + shulker pearl). 4 Shulker Pearls can also be combined with 4 netherite ingots and a Nether Star to make a smithing template to upgrade the elytra. Apply the template in the smithing table with a shulker pearl to add defensive stats between iron and diamond to your elytra.
