Artifacts are rare collectibles you find while exploring Chillverse's 3D world (see the Exploration feature). Each one comes with a rarity tier — common, rare, epic, or mythic — and rewards you with XP the moment you unlock it, along with a notification celebrating the find.
Your collected Artifacts are shown together on your Artifacts page, which doubles as a way to show off to other players what you've found. A handful of Artifacts require an active Chillverse Pro subscription to actually claim, even if you can see that they exist — if one looks locked and you're not currently subscribed, that's why.
