Tides of the Foscari DLC Complete Walkthrough and Abyss Seals in Vampire Survivors

Mastering Lake Foscari and descending into Abyss Foscari introduces environmental puzzle seals that unlock new zones, powerful characters, and unique weapon fusions in Vampire Survivors. By breaking three elemental crystals with specific characters and evolved armaments, players can defeat the world eater Je-Ne-Viv and complete the Foscari academy roster.

Lake Foscari Coffin and the Academy Trio

Beginning in Lake Foscari, follow the map pointer northwest through dense groves until reaching a cluster of mushroom houses. Outside the main fungal dwelling sits the stage coffin containing Eleanor Uziron. Defeating the nearby mob frees Eleanor, who wields SpellString. As Eleanor levels up, SpellStream and SpellStrike appear automatically; leveling all three spells to level 6 unlocks them for all characters, while maxing them out simultaneously fuses them into SpellStrom. Creating SpellStrom unlocks warrior Maruto Cuts, whose sword Eskizzibur evolves alongside maxed Armor into Legionnaire. Evolving Legionnaire in turn unlocks ranger Keitha Muort, whose bow Flash Arrow evolves with maxed Bracer and Clover into Millionaire.

Shattering the Elemental Seals of Foscari

Progressing through the DLC narrative requires destroying three distinct crystal seals positioned across both stages. First, deploy as Keitha Muort on Lake Foscari and evolve her bow into Millionaire. Navigate to the northeastern lakeshore where a green emerald crystal floats across the water; striking this Seal of the Lake with Millionaire shatters the barrier, flooding the screen and permanently unlocking Abyss Foscari on the stage selection screen.

Abyss Foscari and the Je-Ne-Viv Encounter

Within Abyss Foscari, select Maruto Cuts and evolve his weapon into Legionnaire. Travel down into the deep underground chasm to locate the red ruby crystal, the Seal of the Abyss. Destroying it with Legionnaire dispels the oppressive gloom obscuring the southern map sectors and unlocks guardian mage Luminaire Foscari. Next, return as Eleanor Uziron and fuse SpellStrom. Seek out the blue sapphire crystal, the Seal of the Banished, deep in the lower abyss. Shattering this final seal triggers a dramatic boss fight against world eater Je-Ne-Viv. Defeating this monstrosity unlocks witch Genevieve Gruyère and unlocks Hyper Mode for the abyss stage.

Unlocking Sammy, Rottin'Ghoul, and End-Game Evolutions

The remaining Foscari roster requires specialized monster kill counts and weapon upgrades. Surviving 15 minutes as Luminaire Foscari unlocks Prismatic Missile, which evolves alongside a maxed Crown into the prismatic storm Luminaire. Surviving 15 minutes as Genevieve Gruyère unlocks dark spell Shadow Servant, evolving with maxed Skull O'Maniac into Ophion. To unlock caterpillar hero Sammy, travel to the concealed forest glade above the left arrow in Lake Foscari and defeat 6,000 caterpillar mobs. Finally, unlock Rottin'Ghoul by defeating 6,000 ghoul enemies in the lower chambers of Abyss Foscari to the right of the Torrona's Box pickup.
