The Call of Duty Black Ops 3 Zombies map, Der Eisendrache, remains a fan favorite due to its intricate quests and powerful elemental weapons. Among these, the Storm Bow, widely known as the Lightning Bow, is highly sought after for its exceptional crowd control capabilities. Upgrading the base Wrath of the Ancients weapon into this electric powerhouse is an essential strategy for anyone aiming to complete the main easter egg or survive until high rounds.
Initiating the Broken Arrow Quest
To begin the upgrade process, you must first secure the base Wrath of the Ancients bow by feeding the three dragon heads around the castle. Once you have the weapon, head over to the Death Ray trap location on the upper bastions. Look past the castle walls toward a distant weather vane and shoot it with an arrow to drop the broken quest piece near the trap area.
Picking up this broken arrow officially begins your quest lines for the elemental upgrade. This item will occupy your quest slot until the dynamic trials are fully completed. Successfully grabbing this component allows you to move on to the next major phase of lighting up the map beacons.
Lighting the Bonfires Outside the Castle
The next phase requires excellent accuracy as you must locate and shoot three specific bonfires situated outside the playable map boundaries. The first bonfire can be spotted by looking over the wall near the clock tower area. The second is visible from the rocket pad area, positioned high up on the distant cliffside landscape.
The third and final bonfire is located near the double tap perk machine, requiring you to aim carefully over the crumbling castle walls. When hit correctly with a standard arrow, each bonfire will burst into bright, bright blue flames. Activating all three points correctly unlocks the ability to travel below ground for the wall-running step.
Navigating the Undergrade Wall Run
With the bonfires burning, make your way down to the low gravity pyramid chamber to engage the ancient technology. Wait for the antigravity cycle to activate automatically so you can safely run along the stone walls. You must step on five glowing wind symbols without falling down to the stone floor during a single wall-running sequence.
Missing a symbol or touching the ground will reset your progress, forcing you to wait for the next gravity cycle to attempt it again. Once all five panels are successfully triggered, you will hear an audio cue confirming completion. This step creates the elemental cloud canisters needed for filling your arrow with cosmic energy.
Charging the Electric Canisters
The final mechanical requirement involves finding three steaming urns located around the base map and charging them with zombie souls. You will find these containers located near the rocket pad, inside the clock tower courtyard, and right next to the death ray trap. Eliminate approximately five to six zombies near each urn until the blue electricity sparks violently from the top.
Once an urn is fully charged, draw back your bow string while standing near it to coat your arrow tip in lightning energy. Fire this electrified shot directly into the corresponding burning bonfire you lit during the earlier steps. Repeating this sequence for all three locations will return your completed arrow back to the weather vane box for collection.
Forging the Storm Bow Upgrade
Take the newly reforged arrow down to the pyramid room and place it inside the designated elemental chest. You must now sacrifice a final round of zombie souls directly to the chest to fully bind the upgrade to your weapon. Once the collection process stops, interact with the stone altar to claim your completed weapon.
The Storm Bow allows players to completely dominate tight spaces by charging up powerful electric tornadoes. Using this weapon effectively provides the defensive cover necessary to manage the difficult boss fight sequences ahead. Mastering these steps ensures your squad is fully prepared to finish the ultimate castle challenge.
