C204 Wakan Ball
Other than using the naked eye to search for the wakan balls, one could also use their own Student Badge to assist in the search.
The Student Badge was a special Shadow Artifact. As long as the wakan was poured into it, it would be able to reflect a 2D map of the distribution of the wakan. It could ignore the depth of space and detect the reactions of the wakan within a radius of three meters
