How to Get Viridis Reefs
Drops From Nocturnal Echoes

Viridis Reefs's Secret Letter can be obtained from Nocturnal Echoes via the Crystalophile fight. The Crystalophile Nocturnal Echoes is unlocked along with the Nocturnal Echoes system after clearing the Can I Keep It quest.
Use Secret Letters in Covert Commissions

Secret Letters can be used during Covert Commissions to get a chance for the weapon's blueprint and materials to drop. Since Viridis Reefs is a Whipsword, it will only need 2 weapon-specific components. Blueprints are consumed when forging a weapon. You will need a total of 6 blueprints and the corresponding materials to fully max a weapon.
Recomended Characters
| Character | Explanation |
|---|---|
Sibylle | - Viridis Reefs does not offer the same HP bonus that Undying Oneiros does, but it functions as a serviceable weapon for Sibylle since she specializes in Whipswords and can take full advantage of the weapon damage bonus when swinging this weapon. |
