OFFICIAL LOOP

Fight → relic → craft → retest

  1. Use a stable normal-wave layout as the boss baseline.
  2. Watch the first boss attack or position that changes the result.
  3. Test one boss-focused contribution without rebuilding every layer.
  4. Record visible relic rewards and inspect the current in-game crafting screen.
  5. Craft only from the recipe shown in your current version, then repeat the same boss baseline.
