Shadow Niijima (Leviathan) Boss Battle

The boss battle against Leviathan involves the use of buffs and debuffs to beat her before time expires. In other words, you need to pick up the pace against Shadow Niijima to avoid being on the receiving end of a powerful attack. Stack those buffs to keep the Phantom Thieves well-equipped to go first. You’ll also want to cast debuffs to negate the boss’ own charged-up attacks, which in turn also puts her at a disadvantage.
