How to Build Floor Trap Combinations

Elemental Floor Traps

Floor traps sit flush with the ground and trigger when stepped on. The elemental set:

• Fire Floor Trap — ignites the tile.
• Lava Floor Trap — produces lava on trigger.
• Potion Floor Trap — applies a potion effect.
• Tnt Floor Trap — detonates.
• Tnt Mob Floor Trap — TNT variant tuned for mobs.
• Sea Mine Mob Floor Trap — water-themed mob floor trap.

Layering a Trap Hall

1. Dig a corridor and lay a checkerboard of Fire Floor Trap and Potion Floor Trap tiles so mobs cannot avoid both.

2. Put Tnt Floor Trap at the corridor's midpoint to break up groups.

3. Finish the hall with Lava Floor Trap tiles at the exit.

4. For mob-only halls, swap in Tnt Mob Floor Trap and Sea Mine Mob Floor Trap so your own passage stays safe.

5. Add Runny Lava along the walls as a visual deterrent, or place a Runny Lava Bucket to pour it into a side channel.

Supporting Structures

Feed the hall with a Monster Stream Spawner at the entrance. Place Mundane Spike Trap or Withering Spike Trap tiles between the elemental traps to add contact damage. Use Feature Placer to stamp repeated trap sections quickly instead of building each tile by hand.
