Player workbench

Carry Great Inagua's cave map to the Nassau dig without repeating the island pickup or digging at the clue coordinates.

The clue starts in Great Inagua near the docks, but its sketch points to Nassau. The cave approach, Nassau landmark, shovel prompt, and Grey Sails reward are four different checks.

Why this entry is useful

A two-island route that separates the tree-branch cave entrance from the swamp-side Nassau dig and names the reward that closes the trip.

Classic route references agree on Great Inagua's cave near the docks, the Nassau destination near 633, 784, the downed-tree landmark, and the Grey Sails/3,000-Reales reward. Treat both coordinates as orientation leads, then let the current Resynced map, sketch, dig prompt, and reward decide.

Safe first move

Check treasure-map inventory first. If the Great Inagua clue is already owned, keep the cave as complete and route to Nassau rather than starting another branch climb.

Finish line

The Nassau chest opens and the current save confirms Grey Sails Design Plan plus 3,000 Reales; map ownership alone is only the clue leg.

The clue starts in Great Inagua near the docks, but its sketch points to Nassau. The cave approach, Nassau landmark, shovel prompt, and Grey Sails reward are four different checks.

Save proofKnow when it worked

The Nassau chest opens and the current save confirms Grey Sails Design Plan plus 3,000 Reales; map ownership alone is only the clue leg.

How to use it

Preserve the completed leg and inspect only the mismatch

This route has a Great Inagua clue pickup, a Nassau destination dig, and a named ship-design reward. A familiar coordinate cannot establish which leg is complete.

Recovery path

The Nassau chest or reward is missing

If the Great Inagua cave is empty, check whether this map is already in inventory before climbing again. If it is owned but Nassau has no shovel prompt, reopen the same map sketch and compare the western viewpoint/swamp-side house and downed tree around 633, 784; do not return to 845, 468 to dig. If the chest opens but Grey Sails is not confirmed, inspect the actual reward and ship-customization menu before repeating the voyage. Treat the coordinates as classic leads if the current marker differs.

Great Inagua branches → cave map → Nassau tree dig

If the clue is missing, use Great Inagua's Treasure Maps marker near 845, 468 as a classic route lead. From the docks area, climb the nearby tree route and use the downed trunk as the cave approach; confirm that the map actually entered inventory.
If the map is already owned, sail to Nassau. Orient from the western viewpoint/swamp-side house area around 633, 784, compare the clue image to the current shoreline, and follow the visible downed tree toward its base instead of digging at the Great Inagua coordinate.
Open the prompted chest and check for Grey Sails Design Plan and 3,000 Reales in the current reward or ship-customization state. If the label differs, record the actual result rather than replaying a confirmed clue pickup.

Route Plan

How to use Great Inagua to Nassau Grey Sails Treasure Map

Keep the pickup and dig on separate islands. If the clue is missing, the classic route lead near Great Inagua 845, 468 describes a tree-branch approach into a cave close to the docks, using a downed trunk as the entry landmark. If the clue is already owned, the reward is in Nassau: orient from the western viewpoint/swamp-side house near 633, 784 and compare the sketch to the downed tree before checking its base for the dig prompt. These coordinates are classic references, not verified Resynced shovel positions; follow the current map and named reward.

Check inventory before revisiting Great Inagua. If the map is absent, use the current Treasure Maps marker and the cave near the docks; the tree branches and downed-trunk entrance are route landmarks, not a second dig.
With the clue owned, sail to Nassau and use the western viewpoint/swamp-side house around 633, 784 as an orientation lead. Compare the map image and current marker before searching at the base of the downed tree.
Open the prompted chest and verify Grey Sails Design Plan plus 3,000 Reales in the current save. If the map, coordinate, or reward differs, trust the live marker and actual pickup over the old route lead.

Save Checklist

Use these checks before marking Great Inagua to Nassau Grey Sails Treasure Map complete.

Entry type: Treasure Map.
Recommended check: Check map.
Main risk: A cave entrance, nearby island chest, or remembered coordinate is not the Grey Sails reward; the current dig prompt and named chest result are the finish check.
Confirm the marker, reward, or requirement in the current Resynced build.
Open next: locations/great inagua.

Treasure Flow

Treat this treasure route as clue pickup, dig check, and reward decision rather than a single marker.

Clue: Great Inagua's dockside cave is reached from nearby branches; confirm the map in inventory before sailing.
Dig: the clue points to Nassau, around the western viewpoint/swamp-side house near 633, 784; match the sketch to the downed tree and current shovel prompt.
Proof: check the chest result for Grey Sails Design Plan and 3,000 Reales. A map pickup is not proof that the Nassau reward was collected.

Reward Decision

Open the next page based on what the buried chest changes in your save.

Open Jackdaw Upgrades before spending more time on ship power.
Pair the dig route with nearby viewpoints, chests, fragments, or location cleanup before sailing away.

If The Clue Does Not Match

Do not keep sailing in circles when a clue, coordinate, or marker behaves differently in your save.

Reopen the map and confirm the region before moving to the next island.
Check whether a viewpoint, mission state, or fleet reward gates the clue.
Return to Treasure Maps or Map if the marker is not where the route hint expects it.
