Joan (Trial of Courage) · Notre-Dame

Have Infernal Pyre equipped in the Hall of Four Virtues, enter the Trial of Courage, and reach the rematch trigger area. First move away from the jump-slam landing point and fire pillars. Move away from her body while the twin waves charge. Do not merely circle behind her, and do not wait for a supposed first wave to end before turning back to rush an attack. Attack briefly or replenish supplies only after confirming this round of bidirectional attacks has finished and the path through the flames is open. Retreat immediately when you see a spin or pursuit slash starting. Obtain the virtue of Courage after ringing the verification bell; the entrance to Doppelganger opens only when all four virtues are obtained.
