| Great Duke Cannon | Artillery Hall | Adds the Great Duke Cannon. Treat it as a late burst/artillery plan, not an automatic rush: it wants a stable economy and the cannon support chain before it feels efficient. |
| Harpoon Ballista | Ballistics Workshop | Adds Harpoon Ballistas. They are strongest as a committed projectile line for dens and long-run damage, especially once multishot, accuracy, and support upgrades are funded. |
| Monster Bane | Ballistics Workshop | Mithril and silver coat the bolt. Bonus damage to dens. |
| Serrated Mithril Spikes | Ballistics Workshop | The harpoon bolts are now tipped with serrated spikes forged from mithril, greatly increasing their critical hit potential. Harpoons get bonus crit chance. |
| Stardust Calamity Powder | Demolition Shack | Stars and mithril ground into gunpowder, long believed to bring luck in finding their brethren beneath the stone. Demodwarves get bonus Mithril luck, Gem luck, and damage. |
| Demodwarf | Demolition Shack | However their explosions are powerful, dealing high damage and throwing ore far, but they're also destabilizing, producing more falling rocks and greatly raising the calamity bar. |
| Shrapnel Rocks Hate | Demolition Shack | Gunpowder is now riddled with little mithril spikes that upon explosion dig further into the surrounding rock, possibly hitting the weakest and tenderest of spots. |
| Flamer | Flameworks | Adds Flamers. This is the direct fire-damage line: good for straightforward mountain damage and a practical bridge into Flamelord's Wrath runs. |
| Mithril To Blood | Ritual / special | Creates 1-3 dwarves. |
| Mithril To Spirit | Ritual / special | Creates 1 soul. |
| Soul To Bearded Earth | Ritual / special | Creates 1-5 dwarves and 1-7 mithril. |
| The Great Forge | Khazad Greathold | Unlocks and places The Great Forge building. Its building page covers Forge, artifact, rune, enchant, and equipment-style scaling and 18 linked upgrades. |
| Alchemy | Grand Laboratory | Every 20 uses the mithril cost is increased by 1. |
| Laser Cannon | Grand Laboratory | Adds Laser Cannons. Use them as science damage and support scaling; they pair well with gold and late utility plans but still need hauling to keep ore from piling up. |
| Bulldozer | Manufactorum | A treaded metal machine, shaped like a bull and powered by steam and fire. The metal beast can carry a vast amount of ore before it needs returning, and is heavily protected from |
| Reinforced Hull | Manufactorum | Additional mithril plating and structural reinforcements make the bulldozer more resilient to the falling sky. Bulldozer gets bonus HP. |

| Mithril Pickaxes | Miner's Guild | Pickaxes get bonus damage. |
| Thunderboom Tips | Miner's Guild | Runesmiths charge the pickaxe with booming thunder, furiously reverberating inside its mithril prison. Bonus calamity damage multiplier. |
| Sacrifice Beards | Ritual / special | Creates 1-4 mithril and 3-6 faith. |
| Sanctification | Ritual / special | Creates 1 Priest. Scales the gold cost normally. Each use increases the ritual cost by +2 Mithril and +5 Faith. |
| Mithril Divining | Spelunker's Guild | Through star-etched crystals and ancient runes, dwarven seers divine the whispers of mithril veins. Increases Mithril luck of all dwarves by spelunker mithril luck. |
| Spelunker | Spelunker's Guild | Sends Spelunkers on return-timer expeditions that can bring gold, mithril, revealed mithril veins, dens, or injury outcomes. |
| Treasure Hunter | Spelunker's Guild | Sends Treasure Hunters on higher-risk expeditions that can return artifacts, Tier 5 artifacts, mithril, PP, souls, calamities, injuries, or death. |
| Enchant Primal Power | Ritual / special | After casting this ritual select a dwarf or their building. All existing and future dwarves of that type will permanently get +5% damage. |
| Mithril Forging | The Great Forge | Forge path upgrade for spending Mithril on stronger long-run scaling. Buy it when Mithril income is stable enough to support forging. |
| Runesmith | The Great Forge | With a chant and a crescendo of rhythmic pounds, the Runesmith prepares his anvil to sing true, before the final strike forges magic into a rune, instilling power to steel and |
| Mithril Chainmail | The Great Maw | Thick layers of leather and mithril mesh clad the dwarf, hopefully providing some protection against monsters, stray explosives and falling rocks. |
