Attribute stick

Like the debug stick it can only be obtained by commands and used in creative. When you use it to right-click on a block it will open a UI that allows you to customize how it operates under certain conditions, like if it is able to transmit a Redstone signal, if a piston moves it, breaks it, or can't even push it at all. You can also use it to make it appear to be another block because slime blocks aren't exactly very pretty or match every build, it would also make hidden entrances much easier to make, and designers would be able to modify the light levels of blocks to make new possibilities. To see the true blocks or to see if they are modified, there are also true sight goggles which also are gotten by commands which are placed in the helmet slot. They can also modify tile entities to move when pushed (java).
