Mob Farm Tips
Spawning Mechanics
- • Mobs spawn 24-128 blocks from the player
- • Hostile mob cap is 70 per player
- • Light level must be 0 for most hostile mobs
- • Spawn attempts happen every tick (20/second)
- • Spawners activate when player is within 16 blocks
Optimization Tips
- • Build at Y=128+ for fastest despawn below
- • Use water streams to move mobs quickly
- • Carpet prevents other spawns around AFK spot
- • Cave-free perimeter greatly increases rates
- • Trident killers maintain player kill for XP
