This guide details how to generate and direct light beams in Call of Duty: Black Ops 6 Zombies' Citadelle Des Morts Easter Egg. Successfully completing this step is crucial for obtaining the Light Incantation.
Generating and Directing Light Beams
This multi-step process involves manipulating light beams reflected from several crystals.
1. The First Crystal:

Begin in the Dining Hall. Locate the crystal on the north wall, above Vulture-Aid. Shoot the base of this crystal to deflect the light beam downwards. Then, proceed to the second floor's east side of the Dining Hall and shoot the mirror to deflect the beam left, aiming for the second crystal. A successful deflection will illuminate the second crystal.
2. The Second Crystal:

Direct the now-illuminated second crystal's beam towards the crystal above the Lion Knight. This requires shooting the base of the second crystal from the southwest corner of the Dining Hall's second floor.
3. The Third Crystal:
Next, redirect the beam from the third crystal into the Alchemical Lab. Position yourself on the north side of the Dining Hall, facing the crystal, and shoot its base to achieve this.
4. The Fourth Crystal:

Inside the Alchemical Lab, aim for the crystal above the Arsenal Workbench. Stand near the room's exit (on the same side as the crystal) and shoot its base to redirect the beam.
5. Revealing the Paladin's Brooch:
Finally, direct the beam from the last crystal towards a table situated to the left of the Alchemical Lab's entrance to the Dining Hall. Use a similar position to the previous step, shooting the crystal's base to illuminate the table. This action will reveal the Paladin's Brooch, allowing you to proceed with the Light Ritual.
