Master the Call of Duty: Black Ops 6 Zombies Staff of Ice Upgrade! While initially underwhelming, the upgraded Ull's Arrow is crucial for high-round survival and Easter egg hunts. This guide details the upgrade process.

Prerequisites:

Before upgrading, acquire the Staff of Ice itself, either from the Mystery Box or by assembling its three components. Early access to the Dark Aether Nexus (via the Door to Nowhere) is essential.

Upgrade Steps:

Step 1: Freezing Dark Aether Crystals

Quickly freeze three Dark Aether Crystals using the Staff of Ice. Perks like Stamin-Up and PHD Flopper (with Tribologist) significantly aid this process. Optimize your route by strategically targeting lanterns in the tomb area, Shrine of the Hierophants, and 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

Within the Dark Aether Nexus, locate three floating rocks bearing glowing purple Runes. Each Rune displays a unique symbol. Use the Staff of Ice to shoot each Rune (a hitmarker confirms success). This lowers the rocks, making Rune identification easier. A scoped weapon may improve accuracy. The order of shooting is inconsequential.

Step 3: The Rune Symbol Puzzle

After Step 2, a stone wall replaces a portal in the main map. Locate the corresponding area and identify three Runes on the wall matching those from the floating rocks. Shoot these Runes with the Staff of Ice. The portal will reopen, regardless of accuracy. Incorrect symbols result in a mid-air Dark Aether Nexus drop. Multiple failures may require waiting for the next round. Correct symbols lead to a floating rock and a purple orb. Interact with the orb.

Step 4: Orb Escort and Upgrade

The activated Orb begins moving. Aggressively eliminate zombies near the Orb; their essence fuels its movement. Guide the Orb to the central Dark Aether Nexus structure, where it creates a small purple portal. Interact with the portal to upgrade your Staff of Ice into the powerful Ull's Arrow.

Ull's Arrow Abilities:

The Ull's Arrow boasts a devastating charged AoE attack and an alternate fire mode capable of reviving downed teammates, similar to its predecessors in Black Ops 2 and 3.
