Pro Tips
- Floor Choice: Focus on floors 45, 55, and 65 for highest sprite density
- Elevator Method: Use floor 0 → 55 → check/clear → 0 → repeat for maximum efficiency
- Energy Conservation: Only bring minimal food, the coal value outweighs food cost
- Monster Musk: Increases spawn rates dramatically (30 Slime × 1 Bat Wing)
- Only Clear Good Floors: Skip floors with fewer than 3-4 visible sprites

 to make the grind feel more manageable. Each milestone represents about 50 coal on average!
Benefits of the Burglar’s Ring
The Burglar’s Ring’s effect is simple but incredibly powerful: it gives monsters a second chance to drop their loot. This effectively works as a double-drop chance for all monster loot in the game.
For dust sprites specifically, this means:
- Coal: Increases from 50% to approximately 75% effective drop rate
- Coffee Beans: Increases from 1% to nearly 2% chance
- All Rare Drops: Significantly higher chances for scrolls, diamonds, etc.
But the ring’s true value extends far beyond dust sprites. When worn during Skull Cavern runs, it dramatically increases your chances of:
- Iridium from iridium bats and purple slimes
- Prismatic Shards from any eligible monster
- Auto-petters from treasure rooms
- Valuable gems from various monsters
