Abyss Foscari map
(which unlocks the coresponding map:

EDIT: It might take a while to trigger the cutscene. Stay in the area if it does not work immediately. thx to @MechaHeretic for pointing this out.
- 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
- Fight it or let it kill you.
(This achievement does not require to fight it, it just requires the cutsceene to trigger)
If you fight and kill him/it, you also get this acheivement (but it can also be gain later):
