Delver of the Cryptic is a **permanent puzzle-based challenge mode** introduced in Arknights Endfield.

Three spatial sets have released so far. **Cryptic First Revealed** covers the original mechanical puzzles, while **Grotto Survey** and the newest **Artful Realm of Six Cardinals** lean on exploration and chest collection.
