Deep in the Gallery of the Four Virtues inside Notre-Dame, a hidden fight waits behind a lit altar. Once every stained-glass window is glowing, a prompt starts a battle against a dark copy of Rose, a boss whose health bar simply reads “???”. The fight runs quick, but it punishes blind swings, so knowing each attack tell matters more than raw damage.
Quick answer: After the first ending, light all four virtue windows, press INTERACT (R1) at the central altar, then dash behind the “???” boss after its attacks and never hit it while it shows “IMMUNE”.
When the fight becomes available
This encounter becomes available after the first ending, following Dracula’s initial defeat. Its setting is Notre-Dame cathedral; the clues are on plaques beneath the windows. Each of the four virtue windows—Courage, Temperance, Justice, and Prudence—illuminates when you gain its virtue, with the remaining virtues earned after that first ending.
The Courage window can be finished earlier through the Joan rematch behind it. The green Prudence window opens a climbing trial that ends at a bell; strike it and Eleanor grants the virtue of Prudence. The remaining windows are what you set up before the altar will respond.
Light every window and trigger the fight
How to beat the “???” boss
The boss carries one bar labelled “???” and the fight lasts about 55 seconds. Keep moving, hit it after its dashes and landings, jump the floor waves and pillars, and heal when you can. When “HEALED” shows, your healing has triggered. Whip combos and aerial spins both work.
While the boss displays “IMMUNE”, do not attack. Wait for it to come out before you swing.
| Attack | Tell | Counter |
|---|---|---|
| Sword dash and combo | It draws its weapon and crouches before rushing in with slashing attacks. | Dash past it, either through it or around to its rear, then strike its back. |
| Mirror teleport | A tall purple mirror opens | Wait alongside the exit and attack when it comes out. |
| Leap | Jumps high above you | Move clear of its landing area, then attack during its recovery. |
| A mirrored dash paired with a floor wave (“IMMUNE” appears during its charge) | Charges from a mirror with a wave | Jump and air-dash over the wave |
| Spectral beast | Runs along the floor after a teleport | Jump over it or dash through |
| Wings and low sweep (“IMMUNE”) | Sprouts wings for a low dash | Jump over the low dash |
| Floor pillars (“IMMUNE”) | Retreats behind a mirror as dark pillars erupt | Keep airborne by jumping and attacking with the whip in midair. |
