How the Spawner Overlap Tool Works
Add each spawner, enter its X/Y/Z (Java: F3; Bedrock: Show Coordinates), and the map highlights: green tiles = covered by all active spawners, yellow square = best AFK (click to copy). Keep the AFK point inside every spawner’s activation radius (~16 blocks from the cage) and outside the mob-capping zone. The header chips show Active, Overlap %, and a realistic XP/min estimate so you can compare layouts.
Example: Max the Minecraft Player
Max finds a zombie spawner at (0, 40, 0) and a skeleton spawner at (28, 40, 10). He enters both, the tool suggests an AFK at (14, 40, 5) with 100% overlap and ~80 XP/min. He builds a shared water funnel to a single kill chamber and adds a hopper chest for auto-loot.

Master Spawner Rules That Actually Matter
Overlap works only if every spawner stays activated while mobs are funneled into one kill chamber. Keep your AFK spot within ~16 blocks of each cage, preserve spawnable spaces around them, and respect light-level rules so spawning never pauses. The tables below give you the practical numbers and a build checklist you can copy.
| Mob | Activation Radius | Spawn Conditions | Spawn Delay | Notes |
|---|---|---|---|---|
| Zombie 🧟♂️ | ~16 blocks | Light ≤ 0 | 10–40 s | Use water funnel; baby-proof walls |
| Skeleton 🦴 | ~16 blocks | Light ≤ 0 | 10–40 s | Arrows require shield gap |
| Spider 🕷️ | ~16 blocks | Light ≤ 0; 2×2×1 space | 10–40 s | Carpets/strings stop climbing |
| Cave Spider 🕷️ | ~16 blocks | Light ≤ 0; 1×1 mobs | 10–40 s | Fence gates to block gaps; poison care |
| Blaze 🔥 | ~16 blocks | Nether; Light ignores | 10–40 s | Fire Resistance & wither-proofing |
AFK ring beats single point
If spawners sit on a diagonal, mark a 2–3 block AFK ring around the suggested spot. Walking the ring re-activates cages after maintenance without breaking overlap.
Design a Kill Chamber That Never Chokes
Your chamber must collect all streams, prevent backflow, and kill at a pace that matches spawn rate. A two-block headroom chute with a 1×3 slit handles skeletons/zombies; use fence gates for 1×1 cave spiders and lava blades or trident killers for Blazes. The checklist keeps builds consistent across worlds.
| Build Step | Target Size | Materials | Purpose | Common Pitfall |
|---|---|---|---|---|
| Spawner room | 9×9×5 | Blocks, slabs | Guarantee spawn volume | Too small = lower rate |
| Water channels | 8-block runs | Water, signs | Push to chute | Dead spots at corners |
| Drop chute | 1×1 or 1×3 | Walls, gates | Prevent backflow | Spiders wedging sideways |
| Kill method | — | Lava/Trident/Fall | Fast, safe kills | Lava burning items |
| Loot system | 3–6 hoppers | Hoppers, chest | Zero-loss collection | Bottleneck at 1 hopper |
Light leaks kill your rate
Buttons/torches left during construction will silently disable one spawner. Do a full darkness sweep before sealing the room.
Troubleshoot Overlap & Stabilize XP/Min
Low rates usually come from distance (AFK too far from one cage), light leaks, or mobs stuck at corners. Move the AFK tile one block at a time along the green area until overlap returns to 100%, then widen funnels by one block. If you still cap, split the stream into two parallel chutes that merge right before the kill cell—same AFK, double throughput.
