Description

something like what naturally generated waystones do but being able to place them anywhere we want

Describe the solution you would like

or even an item can be added that makes a waystone unbreakable

Anything else?

No response

While an option in waystones to do this natively would be better, you can work around this by using Minecrafts Debug Stick to change the "generated" blockstate to "true". This would achieve the same.
