Companion Sphere created
Once all Focus Blocks are full of energy, the block in the center will be destroyed, and a sphere will spawn. The size, health and damage of the sphere depends on the block used - iron makes smallest sphere, emerald makes biggest and strongest sphere.
Triggering the sphere creation process
You must provide energy to focus blocks. When everything is ready, you must place one of the following blocks in the center - Iron block, Steel block, Gold block, Diamond Block or Emerald Block. The particles will show that the creation is in progress.
Focus Blocks layout
In order to create Companion Spheres, you must place four Focus Blocks in this pattern, where a center is 5 blocks apart from every focus block.
