Artifacts are a special type of gear that you can use to upgrade any hero in Injustice 2 Mobile by adding them to the 6th gear slot. These items boost a hero’s stats and can grant unique passive bonuses to specific heroes.
Artifacts are not easy to come by but if you’re lucky, you can get them through league raids and solo raids (guaranteed in the latter).
Once you get an artifact, you can upgrade it up to the maximum level (level 10) using artifact fragments that you also get from raid drops.
