Describe the feature you have in mind.

just a netherite jetpack for diving in lava, pretty sure this has been requested before
also, please make it available for create 0.5.1b, 1.18.2, amongst other versions so that it can be usable for modpacks

Does this solve a particular problem?

allows us to dive in lava with jetpack enabled, if using the netherite jetpack

Duplicate of #61.
I'm still thinking about it, but all new features will definitely only be implemented against the newest version of create
