Keys from elites

Elite monsters (marked in the bestiary) have a small chance to drop dungeon keys — rusty, iron, mithril, or dragon.

Farm elites that match the tier you want. Drop rates are intentionally low.

A dungeon run

Spend one key from the Dungeons tab. Each run builds a challenge list: trash packs, a miniboss, then a final boss.

Seeded randomness picks which foes appear and slightly scales HP and hits, so every attempt feels a bit different.

Clearing the boss grants gold, materials, XP, and sometimes another key. Death or abandoning fails the run (key is spent).

Copper Crypt (T1), Iron Depths (T2), Mithril Catacombs (T3), and Dragon Vault (T4). Higher tiers need higher combat level and rarer keys.
