Event mystery boxes are rewards from the Deathbeard's Demise seasonal event. Two event mystery boxes are awarded for turning in 4,000 phantom doubloons to Captain Deathbeard, and two big event mystery boxes are awarded for turning in 6,000. Alternatively, 250 phantom doubloons can be directly converted into a mystery box (at the expense of not progressing further in the event, however).
It can be opened for a random selection of rewards, and it is destroyed upon opening. Four empty inventory spaces are required to open it.
These thematic rewards may be obtained by opening an event mystery box throughout the duration of the event.
