Unlock a Special Investigation by clearing a level-300 Anomaly Investigation

Before you go

• Unlock Anomaly Investigations and raise Anomaly Research until level-300 Investigations are available.
• Have a build prepared for the selected high-level target.

Farming steps

1. Open the Investigation list and select a quest whose displayed level is exactly 300.
2. Check its monster, time/cart restrictions, and reward details before departure.
3. Equip a build that can survive the target’s high-level moveset.
4. Complete the level-300 Investigation and claim its results.
5. Check the Anomaly quest list for the one-off Special Investigation unlocked by that clear.
6. Open the new quest and review its exact target and conditions before launching.
7. Complete it if you want its challenge clear; do not repeat the level-300 farm after the one-off unlock unless pursuing other rewards.

• The official note describes a one-off Special Investigation from a level-300 clear.
• Do not assume every subsequent level-300 clear grants another copy.
• Use the displayed Investigation level, not only the monster’s Anomaly rank, to verify eligibility.
