Wonder weapons are some of the most powerful weapons inCall of Duty: Black Ops 6Zombies mode, though acquiring them can be tough. While the mystery box offers a chance for you to get one by chance, crafting them is a more reliable option, though not always easy and requires multiple steps.

With the release of Citadelle des Morts, we didn’t just get one wonder weapon; we got four elemental swords as wonder weapons. Each of them requires you to acquire a sword and upgrade it to its corresponding elemental state. This guide will cover all the steps to obtain the lightning sword, Durendal.

Sometimes, we were able to find it on the ground after dealing with multiple zombies in the underground level, thoughwe’re not entirely sure of the exact conditions.

Doing so will trigger a thunderstorm, causing zombies to spawn and attack you. Your task is to kill zombies andwait for your sword to become electrified.
