Expeditions, Mapping, and Antiquities

The Spelunker's Guild controls Spelunker and Treasure Hunter expedition times, outcome odds, Underground Mapping, and antiquity rewards. Fixed tiers show cumulative effects and base costs; hiring prices and save-driven expedition values are marked dynamic.

  1. Spelunker Dynamic value
    EFFECT

    Hires a Spelunker. Expeditions can return gold, 1–3 Mithril, veins, dens, a dwarf/Scientist, 1–3 PP, a Soul, or an artifact, but can also return empty, injured, or dead. Each return adds 1% Underground Mapping. The first hire has a 180 Gold base price and uses 1 idle dwarf; later prices scale with owned count.

You inquire, we acquire! From the deepest bowels of the underdark, we’ll strip the ruins of every spark!

升級

Thunderline Network:Not all who wander underground are lost. Especially when they’re riding high-voltage ziplines.

Spelunkers take save-dependent value less time to return.

Ancestral Lore:To retrieve ancient ancestral tomes and heirlooms for the noble families is of the greatest prestige. But it requires a certain kind of magical touch, coaxing such intelligence from the Great Mother’s lips.

Increases the odds of spelunkers retrieving PP by save-dependent value.

In general, each time spelunker obtains PP, the base odds are reduced by flat 0.1%.

Drums In The Deep:They are coming.

Increases the chance of multiple dens appearing by save-dependent value when mountain reaches half health or is destroyed.

Explosives Kit:Spelunkers are now kitted with timed explosives, which they plant deep inside the mountain as a parting gift.

Whenever a spelunker returns, he deals damage to the mountain equal to 0.01-save-dependent value of its max health! The % of damage inflicted is increased by 0.0005% per underground mapping (max of 0.5%). The damage cannot exceed 5x of total current DPM.

However, equipping spelunkers with high-explosives makes everyone’s journey far more dangerous, increasing the odds of injury and death by 15% per tier!

Grand Lodge:The guild serves as a grand lodge and trophy hall, where famed and retired spelunkers drink spiced tea and boast of high adventure.

Whenever a Spelunker returns, all dwarves gain +save-dependent value damage for save-dependent value seconds. Whenever a Treasure Hunter returns, they instead gain +save-dependent value damage for the same duration.

Mithril Divining:Through star-etched crystals and ancient runes, dwarven seers divine the whispers of mithril veins.

Increases Mithril-Luck of all dwarves by save-dependent value.

Mithril-Luck increases the chance of mountain dropping mithril.

Relic Raiding:Over the eons, the mountains have swallowed countless dwarven civilizations. Imagine the artefacts that lay in the Great Mother’s stomach below.

Increases chance of dropping artifacts from dens by save-dependent value.

Spelunker:Spelunkers delve deep below the mountains, risking their lives to map the vast undeground network.

Each spelunker takes save-dependent value minutes to return, retrieving one of the following: save-dependent value: +pile of gold, scaled by mountain level and mapping. save-dependent value: +1-3 mithril. save-dependent value: +1 mithril and reveals 1-3 mithril veins. save-dependent value: reveals 1-3 dens. save-dependent value: nothing. save-dependent value: injury, doubling rest. save-dependent value: +1 dwarf or scientist. save-dependent value: +1-3 PP. save-dependent value: +1 soul. save-dependent value: random artifact. save-dependent value: death.

Each returning spelunker increases the underground mapping by +1%.

When spelunker returns, he rests for 2-4 minutes and then sets off again.

Treasure Hunter:Paved by spelunkers, where they dare not go, treasure hunters descend into the deepest bowels below, to raid ancient vaults and perilous ruins.

Each treasure hunter takes save-dependent value minutes to return, retrieving one of the following: save-dependent value: random artifact, whose tier is dependant on mountain level and mapping. save-dependent value: a unique Tier 5 artifact. save-dependent value: 2-4 mithril. save-dependent value: 1-3 PP. save-dependent value: 1 soul. save-dependent value: triggers a trap calamity. save-dependent value: injury, doubling rest. save-dependent value: grave injury, quadrupling rest. save-dependent value: death.

Antiquities Express:It’s not the years, honey, it’s the mileage.

Treasure Hunters take save-dependent value less time to return.

Treasury Acquisition:Dwarves have an entire tree of science dedicated to maximum treasure extraction, which often means turning every nook and cranny, finding every last hidden vault, then blowing it all up just in case.

Whenever any dwarf or weapon destroys a den, it counts as if it had +save-dependent value bonus luck!

Underground Mapping:Represents how much the underground has been cartographed. Spelunkers do this automatically on their own, but gold can always grease its way towards deeper information.

Increases underground mapping by save-dependent value.

Each point lowers the odds of bad outcomes for spelunkers and treasure hunters (up to a max of 300).
