Player workbench

Check the Matanzas mortar-storage plan when ammunition capacity, not damage, interrupts a long naval encounter.

More mortar rounds cannot fix missed shots, low mortar damage, or a hull that fails before the extra rounds are used.

Why this entry is useful

An ammo-capacity diagnosis paired with the Tortuga beach clue, Matanzas waterfall chest and count-based retry.

PowerPyx's Resynced treasure-map guide is the located lead for Tortuga's beach skeleton map near 851, 352 and Matanzas's waterfall dig near 312, 617. This is single-publisher third-party coverage, not official or independent current-save evidence; confirm the clue, live dig prompt, named reward and current Mortar Storage menu state in the save.

Safe first move

Record the mortar count when the attempt fails. Only pursue the Tortuga-to-Matanzas route if you run out while the ship remains fight-ready.

Finish line

The chest reward and storage menu line agree, and the repeated encounter benefits from the additional available rounds rather than a changed firing pattern.

The chest reward and storage menu line agree, and the repeated encounter benefits from the additional available rounds rather than a changed firing pattern.

How to use it

Capacity is not accuracy

The counterfactual is simple: if rounds remain when the fight fails, this plan is not the immediate fix. Preserve the Matanzas dig for a later capacity-limited encounter.

Recovery path

I still have mortar rounds

If the Matanzas waterfall dig is absent, confirm the Tortuga beach map in inventory before repeating the sail. If capacity rises but the fight does not change, inspect range, aim or incoming fire.

Count rounds → dig → capacity retest

Write down rounds remaining at the failure point; a miss pattern is an aiming or range problem, not a storage shortage.
Confirm the Tortuga map near 851, 352, then search left of Matanzas's Mayan Stela behind the waterfall near 312, 617; inspect the chest reward before leaving.
Compare the displayed ammunition capacity in the Jackdaw menu and replay the same fight without changing other ship lanes.

Use 312, 617 for the map check before leaving port.
Match the upgrade lane to the naval fight that is actually blocking you.
