Monsters and drops
Percentages are the drop rates published on the community wiki. Every monster in the mines can also drop pet skins and hats at low rates; those are listed separately on the monsters page rather than repeated in every row.
| Monster | Notable drops |
|---|---|
| Blue Saplings | Sap (70%), monster fang (30%) |
| Blue Rock Clods | Stone (70%), monster shell (30%) |
| Iron Ore Clods | Iron ore (70%), monster shell (30%), sapphire (5%) |
| Green Mushrooms | Cave mushroom (70%), monster powder (30%) |
| Blue Enchanterns | Glass (70%), monster core (30%) |
| Blue Stalagmites | Copper ore (70%), monster horn (30%) |
| Purple Essence Bats | Essence drop (70%), monster wing (30%) |
How to run this biome
Essence Bats are the first reliable Essence-dropping monster, which makes this biome useful when you are saving for perks rather than ore.
