Effect
Reveals hidden rooms and concealed items on the minimap. Treasure chests, secret passages, and hidden events that are normally invisible during standard dungeon navigation are all marked on the map, ensuring you collect every high-value reward each run. The name means "detector" in Italian — a precise description of the relic's function.
Location
Found in the Misty Ruins area, a mid-game region. Prioritize this relic if your build is resource-dependent or you want to maximize per-run material gains.
Rating: ★★★★☆
A reliable quality-of-life and resource-boosting relic that ensures you never accidentally skip hidden rewards. Hidden rooms frequently contain rare gems, bonus coins, and special events that can meaningfully alter the course of a run. Its value is consistent across all dungeon types rather than being situational.
Strategic Value
- Make a habit of checking the minimap frequently — the relic's value scales with how actively you pursue the revealed locations
- Stack with Guiding Light for near-total floor coverage: hidden items and light sources both shown, eliminating blind spots
- Add Milky Way Map for a complete triple-reveal setup: enemies, light sources, and hidden rooms all visible simultaneously
- Hidden rooms are worth a detour even when you're pressed for time — the rewards inside usually outweigh the detour cost
- Particularly strong in early-to-mid game when every extra gem or coin has compounding long-term value
