ForCall of Duty: VanguardZombies players that had given up on the game, the latest update was exactly what they needed to see. The midseason patch saw the addition ofround-based Zombies contentthrough a new objective type, with killstreaks added as well as some Pack-A-Punch camos. However, it is the Tome of Rituals that may be the most impactful addition of all.
Since launch,Call of Duty: Vanguardplayers have claimed that the game’s Artifacts are underpowered. This is understandable, as they are successors to the incredibly strong Field Upgrades fromCall of Duty: Black Ops Cold War. With those abilities able to be upgraded, it makes sense that players would want to do the same inCall of Duty: Vanguard- and thanks to the Tome of Rituals, they can do just that.

How Call of Duty: Vanguard’s Tome of Rituals Works
Call of Duty: Vanguard’s Tome of Rituals provides buffs just likeCall of Duty: Black Ops Cold War’s Aetherium Crystals. However, the key difference is thatCall of Duty: Black Ops Cold War’s Field Upgrade tiers were permanent unlocks. Once players spent Crystals to boost Ring of Fire, Aether Shroud, or whatever other Field Upgrade they enjoy using, the abilities would stay upgraded forever. InCall of Duty: VanguardZombies, things work differently.
The Tome of Rituals sees players getting the ability to upgrade their chosen Artifact four times, with these buffs only lasting for the match where they were purchased. Each of the upgrades requires one Sacrificial Heart, which is acquired by completing one of the Der Anfang objectives. This is a smart decision on the part of Treyarch, as it gives Sacrificial Hearts more of a purpose. With the currency also used for theAltar of Covenants, players will now need to be a bit strategic about when and where they use their Hearts.

All Call of Duty: Vanguard Tome of Rituals Upgrades
Players will get access to four additional upgrade tiers for every Artifact, and some are returning favorites fromCall of Duty: Black Ops Cold WarZombies. The upgrades are as follows.
Aether Shroud
Ring of Fire
The new upgrades should prove useful when going for high rounds in the Void objectives or when working onSeason 2’s main quest easter egg. With Ring of Fire restored to its former glory, and Frost Blast’s insta-kill effect making it more viable in late-game fights, players should be able to rely on their chosen Artifacts a whole lot more.
Call of Duty: Vanguardis available now on PC, PS4, PS5, Xbox One, and Xbox Series X.
