Box of secrets

Both of them dude. And, regarding underwater, the box can be far away of the beach.

Cheers better look harder then i suppose lol

@chris-houlden I found my very first one recently washed up on Forsaken Brink when I joined a random brig crew

I have heard rumors of this Wondrous Box spawning in shipwrecks and even that it can be dug up during an X Marks the Spot voyage, but you'll have the largest chance of finding it washed ashore.

@lt-swag-johnson Only that, rumours

So it can literally be anywhere :p

Have good luck finding it!

There is a very rare chance that it can spawn on a spawn island near a beach.
