I was just wondering what are the best materials to use to make a jump proof, phase proof vault and base. Now I already have a base but I don't yet have a vault but before I do make one if I decide to I wanted to know what are the best materials to use and in what order aka how? -Thanks Masterenderwolf.
Well this was how I built my vault. Don't judge, it's ridiculous, believe me, I know. But if it works it isn't stupid so.. I basically built obby,ironbars,obby,obby. That's a double layer obby outside because I bought too much obsidian. Then I basically filled my vault to the brim with water and for the chests I placed them one block away from walls.
@Masterenderwolf u have seen mine but I'm adding 3 more layers with gaps and water in between them water outside.
Make multiple layers on top sides and bottom with not just obby with water all around will work just fine.
