1. Obtain a shulker core by killing a shulker

2. Use the shulker core and distill it into awkward potions; the result will be potions of advanced levitation which give you levitation 5 for 3 minutes.

3. Next you'll distill a netherite apple into the advanced levitation potions. 

4. The result will be potion of volans, I recommend drinking the normal potions as opposed to splash potions.

5. Drink the potion (you'll become slightly sick because of the netherite apple and you'll levitate a bit.)

6. Once the levitation wears off, you'll have the ability to use creative flight in survival, it isn't cheap though.
