Player workbench

Carry the Petite Caverne map to Tulum for Fire Barrel Storage Ultimate Plan only when barrel stock limits a chase.

Extra barrels matter when a useful stock runs out; the Petite Caverne clue, Tulum dig and harbourmaster install are separate progress states.

Why this entry is useful

A stock-versus-strength test joined to the cave skeleton map, Tulum shipwreck-side dig and same-chase retest.

The Resynced route lead pairs a Petite Caverne skeleton map near 862, 237 with a Tulum southern-beach dig near 40, 372. The older Fleet-to-Isla Providencia chain is not this present Ultimate-plan route; verify the named reward.

Safe first move

Count barrels at the end of a chase first. If stock is exhausted, confirm the Petite Caverne cave map near 862, 237 before sailing to Tulum.

Finish line

The plan is recorded, capacity changes in the Jackdaw menu, and a repeated chase uses the extra stock on a predicted enemy path.

The plan is recorded, capacity changes in the Jackdaw menu, and a repeated chase uses the extra stock on a predicted enemy path.

How to use it

Placement comes before capacity

A storage plan is only the right answer to a stock limit. The chase route has to place barrels in a pursuer's path before more carried barrels add value.

Recovery path

Barrels remain after the chase

If barrels remain unused, practise enemy-path placement. If the Tulum dig prompt is missing, confirm the Petite Caverne skeleton map and recheck the southern beach behind the shipwreck before repeating the sail.

  • Match the upgrade lane to the naval fight that is actually blocking you.

Before Spending

Before Spending

The Jackdaw menu should decide whether this route is worth the sail.

  • Group nearby treasure maps and location checks into the same route.

Naval Retry Prep

Naval Retry Prep

Use the upgrade only when it changes the next sea fight.

  • Restock ammunition before retrying forts, contracts, or legendary ships.
  • Use mortars for safer openings when close approach is the problem.
  • Return to Naval after the plan is installed so the fight route matches the new ship power.
