Big event mystery box (Deathbeard's Demise)

Event mystery boxes are rewards from the Deathbeard's Demise seasonal event. Two of these boxes are awarded for turning in 6,000 Phantom doubloons to Deathbeard. Alternatively, 500 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. Three empty inventory spaces are required to open it.

Special rewards
These thematic rewards may be obtained by opening an event mystery box throughout the duration of the event.

Standard rewards
Two of the following are rewarded.
