All Tome of Rituals Artifact Upgrades in Call of Duty: Vanguard Zombies

Call of Duty: Vanguard Zombies allows you to carry an Artifact that grants you a special power to help defend yourself when summoned. There are four superweapons, each of which is tied to one of the four friendly Dark Aether entities.

With the Season 1.5 update, the developers are introducing a new feature called Tome of Rituals. You can now improve the power and capabilities of your equipped Artifact by up to five levels. The Upgrades can be unlocked in exchange for Sacrificial Hearts, which you collect after each round.
