Operators

[CN] Savage will be given for free to players who didn't have her (through an in-game mail) by signing in for the first time from the start of the event; those who already have her will receive a Savage's Token.png Savage's Token to improve her potential instead.

The following Operators will gain 50% extra Trust (except from Annihilation):

Operator Modules added for Duelist Defenders, Therapist Medics and Dollkeeper Specialists

Headhunting

The fifth Celebration limited headhunting banner, Abyss Corrosion, is featured.

  • Abyss Corrosion also adds Skadi the Corrupting Heart into the Celebration limited Operators' pool.
  • A single Lighthouse in Morning Mist Headhunting Permit.png Lighthouse in Morning Mist Headhunting Permit can be claimed once while the Abyss Corrosion banner is up.
  • Every day, the player can perform one headhunting pull for free at the Abyss Corrosion banner. These free pulls do not transfer over to the next day, so they must be used before the daily reset.
Note: Specter the Unchained will be added into the Celebration limited Operators' pool on the 4th anniversary (May 1, 2023).

Rusty Compass

All SN operations award Rusty Compass.png Rusty Compass when cleared, with more being given when the player clears the operation for the first time. Dusty Atlas operations only awards Rusty Compasses when cleared for the first time.

Rusty Compasses can be exchanged for various items in the Bitterscale Tavern.

The best SN operations to farm Rusty Compasses are SN-8, SN-9, and SN-10 due to their good Oriron Cluster.png Oriron Cluster, Manganese Ore.png Manganese Ore, and Compound Cutting Fluid.png Compound Cutting Fluid drop rates, respectively.

Map Exploration

Instead of a simple node grid listing operations, Stultifera Navis uses a more elaborate map with back-and-forth in areas, thus the progression can be non-linear. There are five maps:

  • Gran Faro, Lost Flagship, and Nameless Ocean, which covers the main operations.
  • Dusty Atlas, which covers extra operations.
  • Mirage, which covers the special operations.

The Gran Faro, Lost Flagship, and Nameless Ocean maps are made up of the following nodes:

  • Landmark: Points out the current location story-wise.
  • Battle: Operations.
  • Event: Advances the player's progress. These also provides flavor text and "happenings", similar to a point-and-click adventure game's, and can award Ship Logs (functionally identical to Voice of Rosebud in Near Light) and A Little Helper components (explained below).
  • Choice: Gives the player a choice to make, which trigger event nodes can be repeated until all options have been exhausted.
  • Story: Interludes.
  • Module: Compete the given task to receive upgrade materials, cosmetic collectible items with flavor text, A Little Help Components, and sometimes Ship Logs.
  • Treasure: Complete the given task to receive rewards. See Treasures for more information.
  • End and Sail: Proceed to the next map.

For the maps themselves, see Stultifera Navis/Maps.

A Little Helper

"A Little Helper" is a mechanic that aids the player in SN operations in a similar way to Stickers in Dossoles Holiday. They are unlocked upon reaching the Messy Junkyard at the Gran Faro map, and its components are available as the player explores the SN maps.

The player need to assemble the Helper's components before they can be used. Each component have two features, but the player can only use one of them at a time.

Miscellaneous

Gourd Valley Mining Area

From May 1, 2022 to May 15, 2022, the player will receive one mining operation every day, which can be used to receive Orundum.png Orundum from three different types of Originium deposits in the Gourd Valley Mining Area, selected at random in each use:

Deposit Value

Originium Ore 500 Orundum icon.png ~ 800 Orundum icon.png
Originium Vein 1000 Orundum icon.png
  • 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, subsequent operations are more likely to reach it. If an Originium Vein was not reached by May 6, May 11, and May 15, then the mining operation on the respective days are 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.
