In-Game App Support

The THGL App https://www.th.gl/companion-app supports Duet Night Abyss now! The player position is visible and it should show some locations in live mode too. Chests and other collectibles are not hidden after you interacted with them - I will work on this. I could only test the prologue map and need your feedback for the other maps.

Quest Database

I've added a comprehensive quest database featuring all 53 quests in the game - including 18 main story quests and 35 side quests (character, world, and story quests).

Features:

  • Quest Chains: Multi-part quests like "Little Researcher" now display the full chain with part numbers (Part 1 of
  1. and easy navigation between parts
  • Linked Requirements: Click on any unlock condition or quest requirement to jump directly to that quest
  • Detailed Info: View chapter names, quest NPCs, auto-start status, and complete reward lists for each quest
  • Smart Organization: Quests are organized by type in the sidebar, with quest chains automatically numbered for clarity
