WHERE & HOW TO FARM

Where to farm

Lake Foscari, at the green Seal of the Lake; play as Keitha Muort with Millionaire.

Abyss Foscari unlocks after Keitha Muort breaks Lake Foscari’s green Seal of the Lake with her evolved base weapon, Millionaire. You need the specified character and weapon form for this progression task. Once the crystal breaks, Abyss Foscari becomes available as the DLC’s second stage, with separate seals leading onward toward Je-Ne-Viv. Complete the unlock once, then use the new stage for later progression.

GET STARTED

How to farm

Before you go

  • Own Tides of the Foscari.
  • Unlock Lake Foscari by reaching level 20 in Mad Forest.
  • Unlock Keitha Muort.
  • Evolve Keitha’s base weapon into Millionaire.
  1. Start Lake Foscari as Keitha Muort and develop her base weapon during the run.
  2. Gather the required weapon evolution resources as they become available.
  3. Complete the evolution so you carry Millionaire before reaching the seal.
  4. Open the stage map and orient yourself toward the green Seal of the Lake.
  5. Travel to the crystal while keeping a build that can survive the route.
  6. Attack the Seal of the Lake with Millionaire until it breaks.
  7. Return to stage selection and confirm Abyss Foscari is available.

Farming tips

  • Complete the weapon evolution before traveling to the seal; reaching it with the wrong weapon form will not meet the requirement.
  • Abyss Foscari’s later seals require different characters and evolved weapons.

Repeat, collect and use

The Seal of the Lake unlock is one-time progression. Repeat only if the crystal did not break or Abyss Foscari did not appear.

Common mistakes

  • Reaching the seal before evolving Millionaire: finish the evolution first.
  • Using a different character: start the run as Keitha Muort.
  • Expecting the DLC stage in the base game: Tides of the Foscari is required.

When to stop or switch

Stop once Abyss Foscari appears in stage selection; switch to the red and blue seal route for the next progression step.
