Requirement

Pick up Eveline's Locket in Vivien's Lab during Chapter 8 ARK Facility

Difficulty assessment

Easy — mandatory pickup

Step-by-step unlock guide

1. Verify you have necessary prerequisites (NG+ status, charm slots, etc.)
2. Reach the trophy trigger location/chapter
3. Equip recommended charm loadout for the trigger condition
4. Execute trigger action (boss defeat, item pickup, route completion)
5. Verify trophy unlock via in-game notification
6. Save immediately after trophy pops to preserve progress

Common mistakes to avoid

• Saving before trigger but losing progress on death
• Selling required items prematurely
• Triggering wrong route variant (especially for ending trophies)
• Missing the optional boss / collectible window

NG+ shortcut method

New Game Plus enables free chapter selection. Use this to farm trophies you missed without replaying the entire game. Infinite Magnum (NG+ unlock) trivializes many boss-required trophies.

Trophy chains

This trophy may chain with related trophies for efficient completion. Plan trophy hunts to maximize per-playthrough progress toward Platinum.
