Levitation Enchantment

You can put this enchantment on weapons and armors (or elytra).

With this enchantment, when you die, your stuff will go up, and stay there until it despawns. So, if you fall in void or in lava, you won't lose your stuff. Maybe, this enchantment could be added in a future end update, making this dimension and void a little bit less scary (Mojang did the same thing in the nether update, making netherite, a material which don't burn in lava). This enchantment would be a treasure one, like mending or frost walker. 

Sorry for bad English :)
