Red Flash in the Dark Full Walkthrough and Details | Monster Hunter Stories 3 ( MHS3 )

It has been with great effort to collect information on the Nargacuga. If their ecosystem rank raises, surely, they'll be easier to observe and study.

This quest is only available after reaching Galyad.

[1] Talk to the Research-Enthused Scrivener.

They are doing research on the Nargacuga but there are only so many available. It would help them a lot if their ecosystem were restored to Rank S.

[2] Make the area habitable again for the Nargacuga.

Defeat the Invasive Nerscylla and retrieve the egg from the endangered den. Hatch and release the Nargacuga into any of the habitats.

[3] Raise the Nargacuga Ecosystem to Rank S.

Collect eggs of Nargacuga, hatch them, and return them to the habitat to keep restoring the habitat.
