GET THOSE CHANNELING TRIDENTS AT THE READY!
Enables the crafting of Zombie, Skeleton and Creeper spawners in vanilla Minecraft enabling you to put a spawner where ever you wish! Just note they are expensive to craft, first, you craft the spawner using the recipe below then craft the spawn egg for the required mob again as below and click the spawn egg on to the spawner.
Be careful however because as soon as the spawner is set as with all other spawners it cannot be moved.
Please Note: When spawner first crafted it will spawn pigs!
