Artifacts are only available to unlock in monthly Events and provide various bonuses. They were first introduced in patch v0.99.55. Artifacts are leveled up with Artifact XP, which is also gained from events (granted retroactively to all participants). Some base experience is also granted for each artifact. Artifact XP distribution can be reset once every seven days. Hover over an artifact's image to see the date you earned it. Artifact XP is increased by 2.5% for each Lineage Level.

Upgrade Cost

The base upgrade cost is 500. The cost of each level increases by this amount. Every ten levels, ten times the increment is added to the cost and the increment increases by 500. The formula for upgrade cost is 500*level*ceiling(level/10).
