How to get Caliburn, Solais, Durendal, & Balmung, Wonder Weapon swords in Black Ops 6 Zombies

The latest Black Ops 6 Zombies map, Citadelle des Morts, introduces four elemental swords as new Wonder Weapons, and each requires a separate set of steps to unlock.

Citadelle des Morts, or “Citadel of the Dead, ” is set in a French castle and the surrounding village. In addition to a new Perk-a-Cola, Ammo Mod, Field Upgrade, GobbleGums, and other secrets, the map introduces four new Wonder Weapons.

The Bastard Sword is a melee weapon found in the castle that can be used to carve up Zombies or defect attacks. The claymore can be transformed into the Caliburn, Durendal, Balmung, or Solais Wonder Weapon, which adds a special elemental attack and passive effect that powers up over time.

Here is a look at what each sword does:

• Caliburn: Dragon’s Fire: Create a fiery maelstrom of burning undead flesh, setting zombies alight and summoning an immense fireball
• Solais: Lion of Light: The warmth of Light courses through you as you send foes screaming into the darkness
• Durendal: Stag of the Storms: Summon thunderous power from the skies, discharging voltaic power to stun and stagger, before an electrical beam serves up a severe searing
• Balmung: Raven’s Shadow: Cast your rotting foes into the Aetherial abyss, warping nearby enemies with a focused liminal tear
