The Staff of Ice stands out as a unique Wonder Weapon in *Call of Duty: Black Ops 6* Zombies. While its initial form might not impress, its upgraded version, Ull’s Arrow, becomes essential for tackling high rounds and completing main quest Easter eggs. Here’s a detailed guide on how to upgrade the Staff of Ice in *Black Ops 6* Zombies.

Prerequisites for Upgrading the Staff of Ice in Black Ops 6 Zombies

Before you can upgrade the Staff of Ice on The Tomb map, you need to meet two key prerequisites. First, you must obtain the Staff of Ice itself. You can either try your luck with the Mystery Box or build the staff by collecting its three parts.

The upgrade process heavily involves the Dark Aether Nexus. To progress, ensure you open the Door to Nowhere early on to access the Dark Aether.

How To Upgrade the Staff of Ice in Black Ops 6 Zombies

Step 1: Freeze Dark Aether Crystals

The first step involves freezing three Dark Aether Crystals found within the lanterns in The Tomb's underground areas. These lanterns are identifiable by their black frames and glowing purple fire.

Use the Staff of Ice to freeze these crystals in quick succession. To increase your chances of success, equip Stamin-Up and/or PHD Flopper with the Tribologist Minor Augment to boost your movement speed. The route you choose is crucial, as is manipulating the lantern spawns. Ideally, wait a few rounds to position the lanterns closer together. Start at the tomb area, then move to the Shrine of the Hierophants, and finally to the entrance of the Subterranean Temple. Ensure one of the lanterns is active, as the one near Quick Revive is too distant. Upon successful completion, you'll hear a quote from Archibald, signaling you to proceed to the Dark Aether Nexus.

Step 2: Floating Rocks in the Dark Aether Nexus

Next, locate three floating rocks in the Dark Aether Nexus, each marked with a glowing purple Rune bearing a unique symbol. These symbols vary each game, so take note of them.

Shoot each Rune with the Staff of Ice. Aiming can be challenging, but a successful hit will be confirmed by a hitmarker, causing the rock to descend, making the Rune easier to target. Consider using a sniper rifle or a weapon with a high-zoom scope to spot the symbols more clearly. The order in which you shoot the rocks doesn't matter, as long as all three are hit.

Step 3: Rune Symbols Puzzle

After completing the second step, a stone wall will replace one of the portals back to the main map. Return to the corresponding area on the map to find a wall with several glowing Runic icons. Identify and shoot the three symbols that match those from the floating rocks using the Staff of Ice. This action will open the portal.

Note that the portal will open regardless of whether you choose the correct symbols. Incorrect choices will lead you to the wrong location in the Dark Aether Nexus, potentially causing you to fall from mid-air. If you fail multiple times, you may need to wait a few rounds for the stone wall to reappear.

If you select the correct symbols, you'll find yourself on a floating rock in the Dark Aether Nexus. Interact with the purple orb in front of you to proceed.

Step 4: Soul Chest Orb Escort

After interacting with the orb, it will begin to move. Follow it closely and kill zombies near it to fuel its movement with a purple trail. Aggressive play is key to keeping the orb moving towards the central structure in the Dark Aether Nexus. Once the orb reaches its destination, interact with the small purple portal that appears to upgrade your Staff of Ice into Ull’s Arrow.
