Player workbench

Route the fire-barrel strength map from Santanillas to San Juan when a successful hit lacks impact.

A barrel that never lands needs placement, an exhausted stock needs storage, and a solid but weak hit may justify strength. The imported Tortuga/Matanzas locations belong to another plan chain.

Why this entry is useful

A hit-versus-stock diagnosis with distinct Santanillas clue, San Juan chest, and one-barrel retest.

The Resynced route lead starts at Santanillas 191, 218 and ends at San Juan 455, 462; older coordinates point elsewhere. The present map, dig prompt, Ultimate-plan reward and harbourmaster menu are the proof.

Safe first move

Record whether the last barrel hit and how many remained; only then confirm the Santanillas hilltop map near 191, 218.

Finish line

The San Juan chest yields the named plan, the strength menu line changes state, and one comparable landed barrel shows the expected improvement.

How to use it

Strength has two prerequisites

The plan is useful only after a barrel reliably hits and enough barrels remain for the target. Keep hit quality, stock and impact as separate observations.

Recovery path

The barrel misses or runs out

If barrels miss, adjust placement; if the stock reaches zero, compare storage. If the San Juan cave dig prompt is missing, verify the Santanillas hilltop map in inventory before repeating the second sail.

Before Spending

Before Spending

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