How to Get Mithril
Mithril comes from dens, spelunking, artifacts, prestige, and a damage-drop progress meter. The reliable path is to combine den clears with mithril-luck instead of waiting for random damage drops alone.
Mithril Sources
Section titled “Mithril Sources”| System | How It Pays Out | How To Improve It |
|---|---|---|
| Dens | Some dens have guaranteed mithril and extra mithril rolls. | Undermined Foundations makes some dens easier; Mithril Compass improves den mithril chance. |
| Damage drops | Each hit adds progress based on damage dealt as a share of mountain max HP, then rolls against a 0.3-1.7 progress step. | Mithril Divining and mithril-luck artifacts/prestige improve this path. |
| Spelunking | Spelunker outcomes can return mithril or reveal mithril veins. | Spelunker starts the system; Treasure Hunter and mapping upgrades deepen it. |
| Artifacts | Some artifacts give direct mithril, den mithril, or mithril-luck. | Giant Mithril Nugget is direct; Greyglitter Dowsing Amulet adds mithril-luck. |
| Prestige | Several permanent upgrades improve mithril starts or mithril-luck. | Greyglitter Leylines and Ascended Mithril Cache are the clearest mithril-focused prestige options. |
| Damage Drop Formula | Each hit adds mithril progress based on damage dealt as a share of mountain max HP. The multiplier starts at 0.03, gains 0.06 per mithril-luck point, caps the luck term at 18, and each normal luck point adds 0.01 mithril luck. A mithril drop appears when progress beats a random threshold from 0.3 to 1.7. |
|---|---|
| Progress Step | 0.3-1.7 |
| Luck Conversion | Luck for hit adds 0.01 mithril luck per point before the mean formula is applied. |
Dens for Mithril
Section titled “Dens for Mithril”| Den | Mithril | Artifact Chance | Loot Range | How To Read It |
|---|---|---|---|---|
| Ancient Vault | 1 guaranteed, 2 extra max | 16% | 5-8 | Best all-around mithril/artifact den when you can break it. |
| Dark Castle | 0 guaranteed, 1 extra max | 9% | 4-6 | Useful early, but usually not the long-term mithril engine. |
| Goblin Den | 0 guaranteed, 1 extra max | 8% | 4-6 | Useful early, but usually not the long-term mithril engine. |
| Mithril Vein | 1 guaranteed, 2 extra max | 1% | 1-4 | Direct mithril target, but weak artifact chance and smaller loot range. |
| Troll Cave | 0 guaranteed, 2 extra max | 11% | 4-7 | No guaranteed mithril, but extra mithril and decent artifact chance make it worth clearing. |
Practical Order
Section titled “Practical Order”| Step | Action |
|---|---|
| 1 | Clear every den you can kill without losing the main mountain timer. |
| 2 | Buy Spelunker and Mithril Divining once the Spelunker's Guild is available. |
| 3 | Chase Mithril Compass, Greyglitter Dowsing Amulet, and Greyglitter Leylines when mithril costs become the wall. |
| 4 | Use Forge Artifact only after the mithril economy can pay for it without freezing other upgrades. |
