Tutorials/Creeper farming

Charged creeper farming is an easy method of creating charged creepers for later detonation to obtain a mob head. As charged creepers are only created when a creeper is struck by lightning, charged creeper farms can be difficult to build. The simplest design is the 'creeper field' design, where creepers are kept in cells below the ground in a flat area.

Channeling trident
You can use a trident with the Channeling enchantment to summon lightning during a thunderstorm. Simply create a collection area from a Creeper farm that is small enough that the creepers will be within 4 blocks of the lightning strike. Then, wait for a thunderstorm and throw a trident at one of the creepers. Note that the creepers must be exposed to the sky for the Channeling enchantment to work. It is recommended to have the Loyalty enchantment on the trident to allow for easy retrieval.

Creeper field
Creeper fields are one of the simplest charged creeper farm designs. They consist of a flat field with 'cells' dug into ground containing creepers. This kind of farm is easiest to create on flat surroundings. Once built, the farm can be set up to supply mob heads with minimal effort. This can be achieved by placing trapdoors underneath the cells leading to a 'detonation chamber,' a room for blowing up other mobs with the charged creepers to obtain heads.

It is possible to make this type of farm more efficient by surrounding the creeper with other mobs. If there is an entity within a 3x3 area of the lightning strike, the lighting strike at that entity instead. Manipulating lightning like this is known as "lightning farming." For more information, see lightning mechanics.

Automatic farm
Automatic charged creeper farms provide a fast way to create charged creepers, however the downside is they are very expensive to build and are not recommended unless the player has a lot of time and resources.
