Mastering the Call of Duty: Black Ops 6 Zombies Staff of Ice Upgrade: A Comprehensive Guide
The Staff of Ice, a unique Wonder Weapon in Call of Duty: Black Ops 6 Zombies, starts weak but transforms into a high-round and Easter egg essential upon upgrade. This guide details the upgrade process on The Tomb map.
Prerequisites:
Before upgrading, acquire the Staff of Ice itself, either from the Mystery Box or by assembling its three parts. Early access to the Dark Aether Nexus, via 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 underground Dark Aether lanterns (black frame, purple fire). Perks like Stamin-Up and PHD Flopper (with Tribologist) significantly aid this step. Optimize your route; a suggested path involves the tomb area, the Shrine of the Hierophants, and the Subterranean Temple entrance lantern (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

Locate three floating rocks within the Dark Aether Nexus, each displaying a glowing purple Rune. Shoot each Rune with the Staff of Ice (a hitmarker confirms success). This lowers the rocks, improving Rune visibility. A sniper rifle or weapon with zoom can assist aiming. The order of shooting the runes is irrelevant.
Step 3: Solving the Rune Symbol Puzzle

Find a stone wall replacing a portal back to the main map. This wall displays Runic symbols; three match the Runes from the floating rocks. Shoot these three matching symbols with the Staff of Ice. The portal will reopen, regardless of accuracy. Incorrect symbols result in a mid-air Dark Aether Nexus drop; wait for the next round if this happens repeatedly. Correct symbols lead to a floating rock and a purple orb. Interact with the orb.
Step 4: Escorting the Soul Chest Orb

After interacting with the orb, it begins moving. Kill zombies near the orb; their essence fuels its progress. Guide the orb to the central Dark Aether Nexus structure, where a purple portal appears. Interact with this portal to upgrade the Staff of Ice to Ull's Arrow.
Ull's Arrow Abilities:
The upgraded Ull's Arrow boasts a powerful charged AoE attack and an alternate fire for reviving downed players, mirroring the weapon from Black Ops 2 and 3.
Call of Duty: Black Ops 6 is available now on PlayStation, Xbox, and PC.
