The Staff of Ice in *Call of Duty: Black Ops 6* Zombies is a unique Wonder Weapon; its base form is underwhelming, but its upgraded version, Ull’s Arrow, is crucial for high-round survival and Easter egg hunts. This guide details the upgrade process.

Prerequisites for Upgrading the Staff of Ice

Before upgrading, you need the Staff of Ice itself. Obtain it either from the Mystery Box or by collecting its three parts. Early access to the Dark Aether Nexus, achieved by opening the Door to Nowhere, is also essential for progression.

How to Upgrade the Staff of Ice

Step 1: Freezing Dark Aether Crystals

Freeze three Dark Aether Crystals rapidly using the Staff of Ice. These crystals are found in underground lanterns (black frame, purple fire). Perks like Stamin-Up and PHD Flopper (with Tribologist) significantly improve your speed. Optimize your route; starting in the tomb area, then Shrine of the Hierophants, and finally the Subterranean Temple entrance lantern is often fastest. Archibald's quote confirms success; proceed to the Dark Aether Nexus.

Step 2: Dark Aether Nexus Floating Rocks

Locate three floating rocks with glowing purple Runes in the Dark Aether Nexus. Each Rune has a unique symbol. Note these symbols; they vary per game. Shoot each Rune with the Staff of Ice (a hitmarker confirms success). This lowers the rocks, making the symbols easier to see. A sniper rifle might aid visibility. The order doesn't matter; shoot all three.

Step 3: Rune Symbols Puzzle

A stone wall replaces a portal back to the main map. Find the corresponding area; a wall displays Runes. Shoot the three Runes matching the symbols from the floating rocks. The portal opens regardless of accuracy, but incorrect symbols teleport you back to the Nexus, potentially mid-air. Multiple failures may require waiting a round. Correct symbols lead to a floating rock and a purple orb. Interact with the orb.

Step 4: Soul Chest Orb Escort

The orb moves; kill zombies near it to power its movement (purple trails indicate progress). The orb settles in the central structure, forming a small portal. Interact to upgrade the Staff of Ice to Ull’s Arrow.

Ull’s Arrow: Upgraded Staff of Ice

Ull’s Arrow boasts a powerful charged AoE attack and an alternate fire for reviving downed players, similar to its Origins counterpart.
