Hey fellow Minecrafters! Just recently I found out how to create an ender crystal with no commands or mods. As you can see here you need a ghast tear on the bottom, ender eye on the middle, and the rest is glass. ArticMage out!
I don't see why they would think of you as a noob. This thread could be helpful to those who didn't know that these were craftable. Maybe add what they are used for to your post as well. That way new players (to minecraft) know what they are used for.
Side note: They have to be placed on obsidian, and to remove them, right click them with a stick like you're eggifying an animal. Returns it to your inventory.
Not a noob move. We learn new things everyday. Such as, andesite can be made from cobble and diorite (I learned this yesterday and was like O.O)
