Artifacts

Artifacts are special items unlocked by finding rare green crystal fragments from enemies, crates, and other usual sources. By collecting three of these artifact fragments, or by opening an artifact crate, you'll be prompted to chose one of three to four random artifacts. The benefits of that artifact then persist through the run.

Trivia

 * Artifacts are named after members of the community.
