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.

Quick Answer

Problem	Do This	If you are stuck
Need first mithril	Clear cheap dens and open Spelunker's Guild when available.	If a den takes too long to kill, upgrade den damage or return after the main mountain is stable.
Damage drops feel dry	Mithril Divining and mithril-luck prestige/artifacts.	Do not wait on random damage drops alone; add a reliable den or spelunking route.
Forge Artifact is tempting	Build mithril income first, then spend on Forge Artifact.	If Forge Artifact freezes your next damage, Alchemy, or unlock purchase, it is too early.
Late mithril wall	Greyglitter Leylines, mithril artifacts, Ancient Vault, and repeatable Spelunker support.	If mithril is the wall, stop spreading gold into side damage branches.

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 mithril 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, Underground Mapping, and Relic Raiding 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.

How damage drops build up	Each hit adds mithril progress based on damage dealt as a share of mountain max HP. Mithril-luck makes that hidden meter move faster, but dens and spelunking are still more reliable when a specific mithril purchase is blocking you.
Progress Step	0.3-1.7
Luck Conversion	Normal luck helps slightly, but direct mithril-luck sources matter more when you are trying to force mithril income.

Mithril Luck FAQ

Question	Answer
Is mithril luck a direct drop chance?	No. It increases the hidden progress multiplier for damage-based mithril drops.
Does normal luck help?	Yes, normal luck on the hit contributes at 0.01 mithril luck per luck point before the cap is applied.
What is the cap?	The formula caps the combined mithril-luck term at 18 before applying the multiplier.
Why do I still see dry streaks?	The progress step is random from 0.3 to 1.7, so even a stronger multiplier can still produce uneven timing.
What should I buy when mithril luck feels weak?	Greyglitter Leylines, Greyglitter Dowsing Amulet, dens, and spelunking support.

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

Step	Action
1	Clear dens that die while your main mountain progress is still moving. If a den survives long enough that the next mountain or timed check stalls, come back after more den damage.
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.

Common Mistakes

Mistake	Fix
Waiting on random damage drops alone.	Use dens, Spelunkers, mithril-luck, and mithril artifacts so the run has reliable sources.
Forcing Forge Artifact too early.	Forge Artifact is strong after mithril income exists. Before that, it can delay the very systems that create more mithril.
Skipping den damage.	Dens are one of the clearest mithril routes. If dens are too slow, improve den pressure instead of ignoring them permanently.
