地窟钥匙

Best route for Crypt Keys: your first key is guaranteed from the Pay Respects Sparrow's Tale — Grave Digger step (community confirmed). After that, the steady supplement is Basic Chest loops across Midrath, Dermak Undercity, and Glades of Andurin — open every Basic Chest along your farming routes and keys will accumulate over time. Crypt Sarcophagi inside the Crypt of the Circade also drop keys, which means gem-farming runs for Gossamer Quartz and Sappheline naturally recycle keys back to you. Sinecure Knight and Midrath Ode/Sinecure camp foe drops exist but are extremely rare per community catalog — do not rely on combat for keys. Hotfix 4 removed keys from dungeon Rare Chests, so focus on Basic Chests and Sarcophagi only.

Pay Respects — Grave Digger — guaranteed

Basic Chest loops — Midrath / Undercity / Glades

Crypt Sarcophagus — gem runs recycle keys

Sinecure Knight patrols — extremely rare foe drops
