Gold and Mithril economy
What coin comes from where, what to spend it on, and what survives death.
Two coins, two lives
Gold lives inside the run: enemies and chests drop it, the merchant charges it, and it dies with you. Mithril is the opposite: it builds up during the run and is banked in full when it ends — whether you die or abandon — to spend at the Forge between runs.
Where gold comes from
| Enemies | 1 to 15 per kill depending on the type — drops on the ground, you have to pick it up |
| Mix chests | 4–24 per opening, on top of the contents |
| Rarity chests | Common 8–18 · Uncommon 12–25 · Rare 18–35 · Legendary 30–60 |
| Apothecary | 300 for turning in their quest |
Where Mithril comes from
| At the start | 550 as a one-time gift in the full game: just enough to complete your first 2 branches in the Forge |
| Mix chests | 0–5 per opening (usually 0–2): opening lots of chests is the steady source |
| Apothecary | 50 per quest turned in |
| Every boss | 25 for killing it —phase or dungeon boss—, on top of its 2 Legendary chests |
Mithril earned during the run is banked when it ends, no matter what: dying doesn't take away anything you've mined.
What to spend it on
Gold, at the merchant — with random discounts that never drop below 25 % of the price — and the sooner the better, since it doesn't carry over to the next run and prices go up 100% per phase (also across the phases of the Dwarven Dungeon, up to ×4 in its phase 4): what costs 25 in phase 1 is 50 in phase 2 and 75 in phase 3 (rerolling too, 20 → 40 → 60). Buying early is worth twice as much as hoarding gold.
Mithril, at the Forge. The first thing is to complete 2 branches of one character: without that you can't start any run or buy Global Upgrades, and until then the full game only lets you buy in the unfinished branches of the race you started. After that, your race's nodes and the Global Upgrades. Resetting a branch refunds its Mithril and costs 35 (the whole tree, 50) —free if, after the reset, no character is left with 2 completed branches—, and refunding Global Upgrades costs 25 for one or 100 for all.
