Choppy Ruin operations are available in the event's second week.
Flooded Seashore is introduced as the new Rotating Mission in November 1, 2021.
The third Celebration limited headhunting banner, Deep Drown Lament, is featured.
- A single Song of the Sea Headhunting Permit can be claimed once while the Deep Drown Lament banner is up.
- Every day, the player can perform one headhunting pull for free at the Deep Drown Lament banner. These free pulls do not transfer over to the next day, so they must be used before the daily reset.
- Note: Skadi the Corrupting Heart will be added into the Celebration limited Operators' pool on Stultifera Navis (late October 2022).
Corrupted Iberian Record
All Deserted Salviento operations award Corrupted Iberian Record when cleared, with more being given when the player clears the operation for the first time. Choppy Ruin operations only awards Corrupted Iberian Records when cleared for the first time.
Corrupted Iberian Records can be exchanged for various items in Barter.
The best Deserted Salviento operations to farm Corrupted Iberian Records are SV-7, SV-8, and SV-9 due to their good Orirock Cluster, Crystalline Component, and Integrated Device drop rates, respectively.

Cautus Valley Mining Area
During the event, the player will receive one mining operation every day, which can be used to receive Orundum from three different types of Originium deposits in Cautus Valley Mining Area, selected at random in each use:
|Originium Crude Ore||300|
|Originium Ore||400 ~ 1700|
- The amount of Orundum received will only be shown after the mining operation is completed.
- If the mining operation does not reach an Originium Vein, the next mining operation(s) are more likely to reach it. If an Originium Vein was not reached by the end of the event, then the last mining operation is guaranteed to reach an Originium Vein.
- Unused mining operations do not transfer over to the next day, so they must be used before the daily reset.
