Calamity System

Selection Formula	A calamity becomes eligible once either calamity level or mountain level reaches its minimum. Higher-tier calamities gain extra weight as calamity level rises, then the game picks from the weighted pool.
Trigger Effects	Each calamity trigger raises calamity level, starts an 8-second calamity window, runs the chosen event, and can reveal a den if the den-reveal upgrade succeeds.
Falling Rock Formula	Falling rocks use a weighted five-rock table. Stronger rock types become more likely as calamity strength increases.

Den Loot

Destruction Artifact Chance	A guaranteed artifact counter takes priority. Otherwise, the den rolls its base artifact chance plus prestige and spelunker bonuses, with den luck adding up to 30 percentage points.
Den Loot Formula	Den loot starts from each item weight and applies den-specific loot multipliers. Gem luck boosts gems, den luck boosts valuable items, and mithril respects extra-mithril caps plus mithril-weight artifacts.
Artifact Selection	Destroyed dens roll from artifacts you have not obtained or collected, excluding boss-only artifacts. Artifacts above the den's max tier can still appear, but their weight is halved.
Artifact Choice	Artifact-choice screens exclude owned, collected, and boss-only artifacts. Higher mountain level adds more weight to higher-tier artifacts, and the offered choices are unique.

Den	Health	Scaling Details	Artifact	Mithril	Loot	Hazards
Ancient Vault	Den HP rolls between 14% and 19% of mountain max HP. After mountain level 100, both ends are reduced by late-game scaling but floor at 1%.

Den Spawning and Placement

Den spawning uses a level-gated weighted chooser, free-space placement checks, and den attack objects.

Den Count Formula	Every mountain starts from one den roll, then makes up to three extra den rolls with chances that rise by level. Spelunker multi-den bonuses multiply those extra-roll chances, with a minimum multiplier of 1.
Weighted Choice	Eligible den types use weights after level and availability filters.
Placement Check	Dens need valid free mountain space before they can appear.
Extra Spawn Sources	Half-health triggers, calamities, spelunking, artifacts, and upgrades can add extra den rolls.

Spawn and Placement Mechanics

Mechanic	Player Meaning	Related Systems
Base den roll	Each mountain starts with a normal den roll, then can add extra den rolls from level scaling and spelunker-related bonuses.	Mountain start
Weighted den choice	Eligible den types are chosen from a weighted pool, so high-weight dens appear more often once they are allowed.	Den type table
Level gates	Some den types need a minimum mountain level or special progression condition before they enter the pool.	Mountain progression
Free-space placement	The game checks for valid open mountain space before placing a den, which prevents overlapping or impossible den positions.	Placement
Half-health spawns	Several effects can add den rolls when the mountain reaches half health or is destroyed.	Spelunker and calamity effects
Special den sources	Calamities, artifacts, and some upgrades can spawn specific den types instead of waiting for the normal roll.	Calamities and artifacts

Falling Rocks and Hazard Defense

Falling hazards are both a calamity system and a den-defense system. The mechanics include weighted rock spawning, runner hit checks, dodge/shield counters, turret destruction rewards, and special den projectile objects.

Falling Rock Formula	Falling rocks use a weighted five-rock table. Stronger rock types become more likely as calamity strength increases.
Calamity Trigger Effects	Each calamity trigger raises calamity level, starts an 8-second calamity window, runs the chosen event, and can reveal a den if the den-reveal upgrade succeeds.
Falling/Hazard Objects	8

Mithril Drops

Mithril is both a resource and a probability system. Hits build random progress toward a drop rather than using a flat per-hit percentage.

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.

Mountain Health and Leveling

This page summarizes how mountain health scales.

Starting Level	1
Health Coefficient	1.115
Base Gold Per Damage	0.5
Max Health Formula	Mountain max HP is max(1, round(base HP x 1.115^mountain level)), using the level-band base HP rules below.
Calamity Bar Percent	The calamity bar threshold shrinks from about 36% of mountain HP at level 1 toward 16% by level 100.
Calamity Bar Max	The calamity bar target is based on mountain max HP and the level-based calamity percentage, then randomized by plus or minus 20%.
Den Count Formula	Every mountain starts from one den roll, then makes up to three extra den rolls with chances that rise by level. Spelunker multi-den bonuses multiply those extra-roll chances, with a minimum multiplier of 1.

Health Base Bands

Levels	Base-HP Rule
1-10	Levels 1-10: base HP scales linearly from 1,200 to 2,100 before the per-level multiplier is applied.
11-50	Levels 11-50: base HP scales linearly from 2,100 to 2,800 before the per-level multiplier is applied.
51+	Level 51+: base HP stays at 2,800 before the per-level multiplier is applied.

Ore Drop Pipeline

This page connects the ore value table to the drop pipeline. Damage and luck feed drop chance, then a count/value allocator can bias toward gems, handle overfill/jackpot cases, and exit early when no valid ore remains.

Max Ore Drops	Mountain levels 1-50 usually drop 1 ore item, with occasional 2-3 item drops. Levels 51-100 gradually shift toward fewer drops, ending around 48% no drop, 47% one drop, 4% two drops, and 1% three drops; level 100+ keeps those odds.
Gem Preference	If a hit deals at least 15 damage and has gem bias, it can force a single gem roll. The chance starts at 12%, increases with gem bias and luck, and caps at 60%.
Gold Per Damage Base	0.5
Primary Levers	Damage share, luck, mithril luck, gem bias, ore values, and selection weights.

Ore and Gem Values

Rank	Ore/Gem	Value	Weight	Kind
1	Mithril	Special resource	100	Ore
2	Massive Pure Gold	1000	25	Ore

How Drop Rolls Work

Mechanic	Player Meaning	Related Systems
Damage progress	Each hit contributes to a hidden mithril/drop progress pool based on damage dealt relative to mountain max HP.	Damage, mountain health, mithril luck
Drop count curve	Early mountains mostly drop one ore item per successful drop. Higher levels add more zero-drop outcomes, so raw hit count matters less without luck/value scaling.	Mountain level
Gem preference	Big enough hits with gem bias can force a gem roll; the chance starts low and caps at 60%.	Gem luck and gem-focused upgrades
Ore value allocator	When a drop happens, the game spends a value budget across eligible ore/gem entries using their values and selection weights.	Ore and gem value table
Overfill and jackpot handling	Very large value budgets can produce overfill/jackpot behavior instead of a simple single low-value ore.	High damage and value modifiers
Mithril routes	Mithril is separate from ordinary gold value: damage progress, den loot, spelunking, artifacts, and prestige can all add mithril paths.	Mithril guide

Ore Reclaim Pressure

Ore on the mountain is not permanent. The reclaim system starts after a minimum uncollected count, accelerates at surge thresholds, and uses emergency cleanup behavior when ore piles get too large. The related tables list runner capacity, gathering speed, stash throughput, and dodge fields beside the reclaim rules.

Reclaim and Pressure Mechanics

Mechanic	Player Meaning
Start threshold	The mountain starts reclaiming loose ore and gems once roughly 350 uncollected pickups are sitting on the ground.
Speed scaling	After that, reclaim speed rises every 15 extra loose pickups. It starts very slowly, then adds 0.6 pickups per second per step, capped at 80 before surge multipliers.
Surge band	At 750 loose pickups, reclaim enters a surge band. By 1050 loose pickups, the surge multiplier reaches 8x and the batch size can grow from 8 up to 58 pickups at a time.
Emergency cleanup	Above 1420 loose pickups, the game treats the pile as an emergency: reclaim speed is multiplied by 23 and the batch size keeps expanding quickly.
What it takes first	Mithril, artifacts, carried pickups, gathered pickups, and deposited pickups are skipped. Regular ore/gems are biased toward cheaper items, with a small preference for pickups closest to the mountain and a 7% fully random fallback.
How to fight it	Solve this with Runner carry capacity, gathering speed, Bulldozer hauling, and Maw/Stonecaller effects that redirect some reclaimed ore away from the mountain.

Runner / Bulldozer Logistics

Object	Role	Carry / Gather	Speed / Dodge	Stun / Deposit / Recovery
Runner	Dwarf Or Weapon	Carry Capacity Base: 1 Carry Capacity: Base carry capacity multiplied by active capacity modifiers. Gathering Timer Base: 2.1 Gathering Timer: Base value multiplied by all active modifiers for this stat.	Move Speed Base: Random speed between 15-18. Move Speed: Speed is capped at its maximum allowed value after modifiers. Dodge Base: 0.1 Dodge: Dodge chance is clamped after all dodge bonuses and penalties.	-
Bulldozer	Dwarf Or Weapon	Carry Capacity Base: 15 Carry Capacity: Base value adjusted by active bonuses and multipliers.	Move Speed Base: 16 Move Speed: Base speed multiplied by active speed modifiers. Dodge Base: 0.07	Stun Duration: Random duration/value between 18-32. Deposit Interval: 0.14 HP Regen Interval: 5 Ores To Throw: Calculated from current bonuses and game state.
Stash	Other	-	-	-

What Gets Tracked

System	Player Meaning
Ore storage	Dwarves and haulers track carried ore/gem payloads until they return them to storage.
Gem Frenzy	Temporary gem-frenzy bonuses can affect carrying and movement while active.
Storage size	Carry-capacity upgrades and bulldozer logistics affect how much ore can be moved before reclaim pressure matters.

Ore Selection

Max Ore Drops	Early and mid levels usually produce steadier ore drops. Past level 51, pure gold farming becomes less about more drops and more about value multipliers, hauling, mithril, artifacts, PP, and gate progress.
Gem Preference	If a hit deals at least 15 damage and has gem bias, it can force a single gem roll. The chance starts at 12%, increases with gem bias and luck, and caps at 60%.

Selection Rules

• Very common ores stay important, but the weighting is softened so they do not completely crowd out rare drops.
• The drop picker filters by remaining damage value; gem bias and luck can let better gems fit into the roll.
• Drops closer to the remaining value budget get preferred.
• Eligible gems get extra weight from gem bias.

What Prestige Tracks

System	Player Meaning
Spend accounting	The game tracks spent and available PP so permanent upgrades can scale cleanly.
Mountain-kill counters	Repeated mountain clears feed several prestige rewards and unlock checks.
Guaranteed den drops	Some prestige effects bank guaranteed den rewards for later mountains.
Pending scientists	Prestige can queue scientist awards that are claimed after the relevant trigger.

Prestige Mechanics

Mechanic	Player Meaning	Related Systems
PP spend accounting	The game separately tracks available and spent PP so permanent upgrades can gate tiers and keep scaling across runs.	Prestige upgrades
Active upgrade storage	Prestige purchases write tier/value state into active upgrade records; stat listeners then read those records during a run.	Upgrade effects
Mountain-kill counters	Several rewards use mountain clear counts as long-term progress, especially for late-game unlocks and repeat scaling.	Mountain progression
Guaranteed den rewards	Some prestige effects bank guaranteed den drops, making den progression less random on later runs.	Dens and artifacts
Queued scientists	Prestige can queue scientist rewards that are granted when the relevant laboratory trigger resolves.	Laboratory
Infinite tier-6 sinks	Late prestige includes repeatable per-ascension sinks for major damage lines, giving PP a long-term outlet.	Late-game ascension

Permanent Upgrades to Understand First

Upgrade	Why Players Care	Best Timing
Swift Start	Starts future runs with runners, which helps early hauling and ore collection immediately.	First few PP if early runs feel slow.
Ancestor's Picks	Permanent miner damage and luck make the basic damage engine stronger every run.	Early damage foundation.
Marching Orders	Runner speed reduces the time ore sits exposed to mountain reclaim pressure.	When hauling, not damage, is the bottleneck.
Fated Finds	Guarantees artifacts from the first destroyed dens, turning den clears into more reliable build starts.	Once you can kill dens consistently.
Greyglitter Leylines	Adds mithril-luck to every dwarf, improving the damage-based mithril drop path.	When mithril costs start blocking upgrades.
Key Master	Improves Ruby Key, Sapphire Key, and Emerald Key drops for special mountain progression.	When the Triple Seal Gate path is the goal.

Action Mechanics

Mechanic	Player Meaning	Related Systems
Runes	Runes act like repeatable build-shaping upgrades, mostly changing damage, luck, speed, crits, or cooldowns.	Great Forge
Enchants	Enchant-style effects add temporary or limited-use modifiers, then scale through upgrade tiers and prestige bonuses.	Forge and prestige
Rituals	Rituals are active buttons with cooldown and cost hooks; cost reducers and cooldown modifiers are the main scaling levers.	Shrine and forge
Transmutation	Transmutation effects convert one resource or object interaction into another, usually around mithril, soul, ore, or gems.	Geode/Laboratory
Boons and nukes	Large active effects use the same state pattern: unlock the action, apply a cooldown/cost, then scale the payload from tiers and modifiers.	Late active upgrades

Timed Effects

System	Player Meaning
Artifact timers	Temporary artifact effects track whether they are active and how much time remains.
Ritual cooldowns	Ritual-style actions use cooldown and cost modifiers before they can be used again.
Upgrade tiers	Rune, enchant, and transmutation effects scale from current upgrade tiers.

Spelunking Returns

Spelunking uses worker timers, weighted outcomes, return queues, underground mapping, and expedition reward scaling.

Spelunker Rewards	Gold, mithril, mithril veins, den reveals, PP, souls, artifacts, new workers, injury, or death.
Treasure Hunter Rewards	Artifacts, unique Tier 5 artifacts, mithril, PP, souls, trap calamities, injury, grave injury, or death.
Underground Mapping	Every returning spelunker improves mapping, which feeds several scaling upgrades.
Main Safety Artifact	Stonewarden's Pact prevents Spelunkers and Treasure Hunters from dying.

How It Works

Part	Player Meaning
Return timers	Spelunkers use saved return timers; speed and rest modifiers change how quickly expeditions come back.
Outcome rolls	Return outcomes are weighted rolls, so upgrades that mention treasure, PP, artifacts, or better outcomes improve what comes back.
Underground mapping	Underground Mapping is tracked separately and feeds upgrades that scale damage, expedition quality, or late-game returns.
Return queue	Returned expedition text and rewards are queued so multiple spelunkers can finish without losing messages.

Tracked State

System	Player Meaning
Workers	Each spelunker has alive/resting/travel state while an expedition is out.
Return queue	Finished expedition messages and rewards queue up before they are shown.
Underground mapping	Mapping progress is tracked separately and feeds related upgrades.
Visual state	The game also tracks visual movement state for spelunker animations, but it does not change the strategic takeaway.
