Forcefield

A block that’s made by doing these steps:

First, craft a “barrier block”, yes the one you can get with commands. It is crafted with 4 void ingots(see my 1st page I ever made on this wiki for how to get), 2 Redstone blocks, 2 nether stars and 1 netherite block. Your gonna need 2.

Now go into the void dimension(again see my 1st page) and place it on the ground. This will turn it into reinforced bedrock.

Now you need wither bone meal. To get simply put wither skeleton skull into a crafting slot.

Place the wither bone meal onto the reinforced bedrock and over time(this may take some time). Some special endermites are gonna spawn and eat away at the block which leaves it revealing a chest. The chest has 2 void scraps and a new item called a forcefield core as well as a broken barrier block.

Go back to the over world and put this into a crafting table along with 2 broken barrier blocks, 2 end crystals and 1 elytra to craft this.

The block itself can be placed down and then right clicked to bring up a menu where you can turn it off or on, how big it is gonna be(max of 15x15x15), what mobs get effected by it and if other players can pass through or not. Any mobs not selected to pass through will not be able to pass through.
