Mastering the Staff of Ice Upgrade in Call of Duty: Black Ops 6 Zombies
The Staff of Ice, a unique Wonder Weapon in Call of Duty: Black Ops 6 Zombies, boasts a surprisingly potent upgraded form—Ull's Arrow—essential for tackling high rounds and Easter egg challenges. This guide details the upgrade process on The Tomb map.
Prerequisites:
Before upgrading, you need the Staff of Ice itself. This can be obtained from the Mystery Box or by assembling its three components. Early access to the Dark Aether Nexus, achieved by opening the Door to Nowhere, is crucial.
Upgrade Steps:
Step 1: Freezing Dark Aether Crystals

Freeze three Dark Aether Crystals rapidly using the Staff of Ice. These crystals reside within glowing purple Dark Aether lanterns found in The Tomb's underground sections. Perks like Stamin-Up and PHD Flopper (with Tribologist) significantly aid this step by boosting movement speed. Optimize your route; a suggested path involves the tomb area, the Shrine of the Hierophants, and the lantern near the Subterranean Temple entrance (avoiding the lantern near Quick Revive due to distance). Successful completion triggers a quote from Archibald, signaling progression to the Dark Aether Nexus.
Step 2: Targeting Floating Runes in the Dark Aether Nexus

Within the Dark Aether Nexus, locate three floating rocks bearing glowing purple Runes. Each Rune displays a unique symbol. Record these symbols. Use the Staff of Ice to shoot each Rune; a hitmarker confirms a successful shot. Shooting the Rune causes the rock to descend, improving visibility. A scoped weapon can aid accuracy. The order of shooting is irrelevant.
Step 3: Solving the Rune Symbol Puzzle

Return to the main map. A stone wall will replace a portal. Find the corresponding area and locate a wall with Runic icons. Shoot the three icons matching the symbols noted in Step 2 using the Staff of Ice. This reactivates the portal. Note: The portal opens regardless of symbol accuracy; incorrect symbols result in a mid-air drop in the Dark Aether Nexus. Repeated failures may require waiting for the next round.
Step 4: Escorting the Soul Chest Orb

After successfully completing Step 3, interact with the purple orb that appears. The orb will move; maintain proximity and eliminate zombies near it. Killed zombies contribute purple energy to the orb, fueling its movement. Guide the orb to the central structure in the Dark Aether Nexus. Interact with the resulting purple portal to upgrade the Staff of Ice to Ull's Arrow.
Ull's Arrow Abilities:
Ull's Arrow retains the original Staff of Ice's abilities but adds a powerful charged AoE attack and an alternate fire mode for reviving downed teammates.
