Dark Detector
A shared component controlled through the Hogwarts Loyalty Track and required by three of the six Defence Shields.

Reference facts
Effect & use
Hold it while leading the eligible Loyalty Track positions. If you exchange it for a Defence Shield, move your track pawn back three spaces and return the Detector; it passes directly to another eligible House Player if one is already at space five or higher.
Where to find it / how to resolve it
Advance your Loyalty Track pawn to at least the fifth space and ahead of the other players. The final-space handover rule also awards it to a newly arriving player when that space is already occupied by its holder.
Restrictions & timing
- Ties use the rulebook’s first-to-reach priority; the final space has a separate handover rule.
- A shield showing a D.A. Coin cannot be paid for with the Dark Detector.

Consistent terms, section search and two-side teaching
Unified 35 sourced English–Chinese terms and registered all three open rule questions. Search and guide backlinks now lead to matching sections in the current language. Added card-flow diagrams, conditional Dark Arts lessons and exact movement allowances alongside the five existing House comparisons.

Content quality work in this revision
Added a 24-category component catalogue, nine sourced card examples and a rechecked Alohomora entry; the catalogue remains an identified sample rather than a complete Acquire Deck. Added a complete setup and first-round walkthrough with a player-count checklist, cross-links across all eight guides, reference information boxes, a clarification register, page-specific history and local correction drafts. This records reviewed preview content, without announcing the custom-domain launch.
