Hero Artifacts
Hero artifacts are an essential part of upgrading. There are three types of artifacts. The maximum artifact level is 100.
01
Artifact Weapon
Each hero has a unique Artifact Weapon. When a hero uses their first skill, Artifact Weapon grants a bonus to the whole team for nine seconds.
Note
Celeste is the exception. Her Artifact Weapon works only for 4.5 seconds.
Artifact Weapon bonus has an activation chance depending on its star rank:
-
1st star — 30% activation chance.
-
2nd star — 60% activation chance.
-
3rd star and more — 100% activation chance.
You can see the bonus timer and its icon in the upper-left corner of the game screen. Tap on the icon to see the bonus' name and stats.
