This can be done one "harder" run or two easier runs.

But before this one, you have to gain these achievements

The Abyss Foscari achievement in Vampire Survivors worth 9 pointsWith Keitha, break the Seal of the Lake.

The Luminaire Foscari achievement in Vampire Survivors worth 9 pointsWith Maruto, break the Seal of the Abyss.

Edit: Try to get the Luminaire (Prismatic Missile + Crown )
This summons Luminaire Foscari into the fight and she deals massive damage.
Credits to Cobb AUS for pointing this out.

One-run strategy:
- Use Eleanor Uziron
- Gain Spellstorm (combine Spellstring+SpellStream+Spellstrike)
- Approach Je-Ne-Viv (run south-east and turn westward when you reach the waterfall area, pass by the place of the Maruto related seal/crystal, keep the westward path and go north as soon as possible; you should end up next to a seal/crystal - you basicly follow the path of a giant U on the map)
- Stand next to it until a cutsceen plays
This should also trigger this achievment to pop (after game)

The Genevieve Gruyère achievement in Vampire Survivors worth 10 pointsWith Eleanor, break the Seal of the Banished.

- He/it aproaches you and you get teleported away/lose your gear.
- Pick up your gearpieces and fight him/it (mine got reverted to there unbuffed forms)
[- If you die, continue at "2nd run" in the two-run-strategy]

Two-run-strategy:
1st run:
- Use Eleanor Uziron
- Gain Spellstorm (combine Spellstring+SpellStream+Spellstrike)
- Approach Je-Ne-Viv (run south-east and turn westward when you reach the waterfall area, pass by the place of the Maruto related seal/crystal, keep the westward path and go north as soon as possible; you should end up next to a seal/crystal)
- Stand next to it until a cutsceen plays
- He/it kills you

2nd run:
- Use a character you like (or just use Queen Sigma)
- Power up
- Return to him/it
- Kill him/it (you can kite it around the stones north of its spawn)

(Since I completed this en passé, please let me know if I recalled something wrong/have an error)

I'll add that to make the fight even easier, try to have the prismatic missle upgrade.
(crystal ball looking item + Crown )

This summons Luminaire Foscari into the fight and she deals massive damage.

Great guide!

Thx I had no idea where this boss was

Thought I'd mention that this boss fight bugs out/crashes for me on Xbox (Series X), I tried it a few times and once the second phase starts (when you lose your weapons) the boss freezes in place and sometimes sometimes the game crashes. It works fine on PC though.

@xDAKx Didnt happen to me, did you try reinstalling the game?

By eV Deadline on 15 Apr 2023 14:05

@xDAKx froze on my Series X as well. Went back with Queen Sigma and beat it in about 10 seconds.

Yeah Froze for me on Series X also. But easy enough to redo.

In Abyss Foscari, at the location of Seal of the Banished, there is a boss-ish creature (Je-Ne-Viv). You need to beat that.

I fought it right after breaking the seal, not sure how that works but all my weapons from the dlc and my evolutions were gone. At some point, Prismatic Missile appeared next to me and kept appearing till i reached max level. (I took Prismatic Missile before I started the fight so not sure if you will receive unless you already found and took it.)

Refer to Genevieve Gruyère (5G) for how to access this boss fight. Basically, you need to break the Seal of the Banished in Abyss Foscari. Doing so frees this boss, and you'll get sucked into a boss fight in a new area with all your weapons wiped out (but you'll still have your items). The Boss will be stealing life from you, and you're forced to rely on the drops of Prismatic Missiles. At least, that's the only weapon that was dropping on the ground around me and the fight. Within a minute or two, I had picked up enough Prismatic Missiles to have it fully leveled up. I also got a Magic Wand and maybe another weapon. I'm not sure if the weapon drops are random, but basically you want to be constantly looking around you for weapon drops to add to your arsenal so you can actually damage the boss. In addition to the boss, those red fire exploding enemies from the second stage of the game show up as adds during this fight.

What was very strange about this fight was that I had no health bar after I got sucked into the fight. I have no idea if this was a bug of intentional, and whether or not I was invincible or just couldn't see my health. From what I could tell, I was never close to dying, I just circled around the boss, picking up all the weapon drops I could find, and just waited until the boss finally died. When the boss dies, your run will automatically end and you'll unlock this achievement.
