X Marks the Spot is an object in the Shipwrecked DLC that appears only after its location has been revealed by reading a Message in a Bottle. It appears as two X-crossed bones over disturbed soil. It can be dug up with a Shovel or shot with a Boat Cannon to reveal Bone Shards and a Chest containing several pieces of treasure. Players should be cautious as one treasure preset spawns 3 Snakes when dug up.
When worn, Woodlegs'Lucky Hat creates a new X Marks the Spot every 800 seconds (slightly more than 1 Day and a half). If worn by a NPC, such as a Wildbore or a Prime Ape, it only has a 66% chance to spawn a treasure.
During a Volcano eruption in Dry Season, if a Dragoon Egg happens to fall on an X Marks the Spot, it will be dug up, burning the Chest and all flammable Items it contained.
There are fixed presets of the treasure chest loot, mixed with some random loot plus some chance loot.
Only one of these items is always added to the treasure chest based.
Each item in this loot table has its own independent chance of appearing, meaning they can appear in any combination or not at all.

Most random loot outcomes have the same loot table, all equally likely:
Standard Chance Loot:
Most chance loot outcomes have the same loot table: (25%)(25%)(10%)
