This can be done one "harder" run or two easier runs.
But before this one, you have to gain these achievements
Edit: Try to get the Luminaire (Prismatic Missile + Crown )
This summons Luminaire Foscari into the fight and she deals massive damage.

Cobb AUS for pointing this out.
https://vampire-survivors.fandom.com/wiki/LuminaireOne-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)
- 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]
