Mob Grinding Utils — Reference

Mob Spawner

The Mob Spawner block is the heart of the farm - it clones a chosen mob over and over.

• Set the target with a Mob Swab. Right-click a living mob with a Mob Swab to sample its type, then apply the swab to the spawner to lock in what it produces.
• Feed it experience. The spawner runs on stored experience (supplied via an XP Tank), spending it to keep producing copies of the sampled mob.
• Continuous output. Once set and fueled, it spawns that mob type directly above itself, ready to be pushed into your kill zone.

Because you choose the mob, you can build a farm for exactly the drops you want - bones, string, gunpowder, rotten flesh, or rarer mob loot.

Killing Blocks: Spikes & Saw

Two blocks turn herded mobs into loot:

Spikes

• Iron Spikes are placed on the floor and damage mobs that walk or are pushed onto them.
• Spikes also drop the mob's experience, so the XP can be collected rather than lost.
• Mobs killed by spikes do not count as player kills, which keeps the farm fully automatic.
• Diamond-tier spikes deal more damage for tougher mobs.

Saw

• The Saw is a spinning blade that slices any mob passing over or beside it.
• It works well at the end of a fan-driven corridor, cutting down the stream of mobs as they arrive.
• Like spikes, it lets the farm run hands-free.

Pick spikes for a flat kill floor, or the saw for a powered blade at the end of a conveyor path.

Other Tools & Upgrades

Supporting items round out the kit:

• Mob Swab - sample a living mob's type, then apply it to a Mob Spawner to set what it produces.
• Sieve - process certain materials as part of resource gathering.
• Saw upgrades - improve the killing blade's reach or power.
• Tank upgrades - increase the storage capacity of the XP Tank and Absorption Hopper.

Craft these as you scale up, turning a small starter farm into a high-throughput mob grinder.

Building a Mob Farm

A typical automatic farm comes together like this:

1. Capture or find the mob you want, then swab it with a Mob Swab.
2. Place a Mob Spawner, apply the swab to set its target, and supply it with experience from an XP Tank.
3. Lay out Fans so their airflow pushes the spawned mobs along a floor toward a single point.
4. At that point, place Spikes or a Saw to kill the herded mobs automatically.
5. Set an Absorption Hopper within range to collect every drop into a chest and route the XP into the XP Tank.
6. Add an XP Solidifier to bank surplus experience as solid blocks you can carry.

The whole loop runs with no redstone - design it once and it spawns, herds, kills, collects and banks on its own.
