Big event mystery boxes are reward items available from the Mental Health Awareness Week event. They are earned by converting the charity tokens at a rate of 500 tokens per one event mystery box.
When opened, big event mystery boxes yield a total assortment of five rewards, and the box is destroyed. Five open inventory spaces are required to open a box.
