Buried Treasure & Shipwreck Loot Guide

Buried treasure isn't something you stumble on — every chest is placed by a map, and every map comes from one of exactly two underwater structures. Here's the actual chain, what's in each chest, and where fishing genuinely fits in versus where it doesn't.

Where treasure maps actually come from

Shipwrecks are the reliable source. A shipwreck can generate up to three chests — a supply chest (crew quarters, mostly food), a treasure chest (upper stern, iron/gold/occasionally diamonds), and a map chest, which is guaranteed to contain a buried treasure map whenever the shipwreck has at least two chests present.

Ocean ruins are the backup source. Most ruin pieces that generate a chest at all have roughly a 42% chance that chest holds a buried treasure map instead of regular loot — reliable enough to check, not reliable enough to plan around the way a shipwreck's map chest is.

What's actually in a buried treasure chest

Every buried treasure chest guarantees exactly one Heart of the Sea — the item used to craft a conduit, and otherwise unobtainable anywhere else in the game. Beyond that guaranteed item, Java Edition's loot table rolls from a pool that includes iron ingots, gold ingots, emeralds, diamonds, prismarine crystals, TNT, and cooked fish. Bedrock Edition uses a different pool that can additionally include things like chainmail armor pieces, name tags, and leads.

Fishing's real connection: Luck of the Sea

This is worth being precise about, because it's easy to overstate: Luck of the Sea does not increase your odds of catching a buried treasure map from fishing. Treasure maps are a shipwreck/ocean-ruin loot item, not part of the fishing loot table at all. What Luck of the Sea actually does is increase how often a catch lands in fishing's separate "treasure" category — enchanted books, enchanted fishing rods, enchanted bows, name tags, saddles, and nautilus shells — each level shifting roughly 2% of catches from junk into that treasure pool without touching the item quality within it.

The real overlap between fishing and treasure hunting is thematic, not mechanical: both revolve around the ocean, and a maxed-out fishing rod is worth having regardless of whether you're actively treasure-hunting, since every AFK session also passively farms nautilus shells and enchanted gear. See The Ideal Fishing Rod Enchantments for the full build.

Frequently asked questions

Does Luck of the Sea help you find buried treasure maps?

No. Buried treasure maps come exclusively from shipwreck map chests and, less reliably, ocean ruin chests — they're not part of the fishing loot table. Luck of the Sea only improves your odds of a fishing catch landing in the separate treasure category (enchanted books, rods, bows, name tags, saddles, nautilus shells).

Is a shipwreck or an ocean ruin a more reliable source for a treasure map?

A shipwreck, by a clear margin. Its map chest is guaranteed to contain a buried treasure map whenever the shipwreck has at least two chests, while an ocean ruin chest only has roughly a 42% chance of holding one.

What's guaranteed to be in a buried treasure chest?

Exactly one Heart of the Sea, every time, in both Java and Bedrock Edition. Everything else — iron, gold, diamonds, emeralds, prismarine crystals, and the rest — comes from a loot pool and isn't guaranteed on any individual chest.

What is a Heart of the Sea actually used for?

Crafting a conduit, an underwater structure block that grants Conduit Power (improved underwater vision and breathing) to nearby players. It has no other crafting use, and buried treasure is its only source.

Can shipwrecks generate without any chests at all?

Yes — a shipwreck's loot chests depend on which sections of the ship actually generated intact, and a heavily broken shipwreck can end up with zero or just one chest. The guaranteed-map rule specifically requires at least two chests to be present.
