How do you make a healer in pixelmon?

To make a healer in Pixelmon, you'll need to gather the necessary materials: four aluminum plates and one diamond. First, smelt aluminum ore to create aluminum ingots, then use a crafting table to shape the ingots into plates. Finally, combine the four aluminum plates with the diamond in the crafting grid to create the healer. Place the healer block in your desired location, and it will allow you to heal your Pokémon.
