The main storyline of the Age of Great Voyages features navigators with different roles and abilities, who will join us as we progress through the main missions. Many newcomers, after obtaining these navigators, may not be clear about their capabilities and development directions, which can lead to a waste of character potential. To avoid this, let's introduce the main storyline navigators one by one.

1. Helen
Helen is positioned as a trade support. Her "Course Deviation Protection" has a 50% chance to immediately correct the course when automatic navigation goes off track. You can cultivate her alongside Hannah, which together brings up to 70% course deviation protection, quite effective. Her "Disaster Guard" reduces the occurrence probability of negative natural disasters during voyages, making her essential for adventure players.

2. Felicia
She joins after completing the Red Wraith's Fall mission and defeating Maeve. As a gunner, Felicia is indispensable for artillery players. Her "Critical Hit" enhances various compatible cannons, and her "Sail Rending Mastery" increases the chance of all cannonballs rending sails by 5%. If you are playing as a support gunner on a cannon ship, it is recommended to pair her with chain shot cannons, with an occupation pairing of a Senior Commander from the Naval Officer series, to better utilize her skills.

3. Demir
Demir joins the team after acquiring the Western Mediterranean Port Entry Permit and completing the Justice and Power quest. His role is supportive. "Drifting Object Discovery" gives a 10% chance to find an additional drifting object at sea, which can be paired with the advanced lookout station available in mid-to-late game ship modifications. "Mine Defense" protects against players skilled in mine attacks. Due to his skills lacking significant highlights, he is not highly recommended for priority cultivation.

4. Ricardo
Ricardo joins after obtaining the Eastern Mediterranean Port Entry Permit and completing the Unresolved Victory. His key skill is "Crafting Assistant," which adds 10% to crafting support, increasing the great success rate of production and adding 20% to the great success rate of commission production, while also speeding up production by 50%. It's important to note that navigators with such auxiliary skills are rare, especially since the great success rate is influenced by various factors. Upgrading Ricardo to level 41 to unlock the crafting support bonus is crucial for us.

5. Vargas
Vargas joins once the player reaches a comprehensive level of 100, obtains the West African Coast Port Entry Permit, and completes the Elegy of the Departed. From his skills, it’s clear he specializes in mines, suitable for players planning to take the support route, setting up mines. It is suggested to pair him with the Advanced Commander under the Scout Tactician profession. Additionally, as a character with a command advantage, he can also serve as a deputy captain.

6. Igor
Igor joins after reaching a comprehensive level of 100, obtaining the South Atlantic Port Entry Permit, and completing the Prelude Before the Final Chapter. His profession is Mercenary. The first skill, "Emergency Handling," is a versatile move, useful in both naval and land battles; "Confusion Defense" reduces the probability of confusion by 6%, which is very beneficial for melee combat ships, as accidentally being attacked while charging towards enemies can trigger a confusion state, greatly reducing attack and defense, making subsequent battles unfavorable. This skill can lower the occurrence of confusion, and it's recommended to pair it with the Military Intelligence Research Lab, further reducing group confusion by 3%, effectively lowering the probability of confusion. His "Fire Defense" is very suitable for traders, but as it is the third skill, the cost of cultivation is high. For players preparing to engage in trading and melee combat, it's recommended to cultivate this, preferably paired with a fireproof warehouse.

The above are the main storyline navigators of the Age of Great Voyages. The introduction covered the roles and abilities of characters obtainable through the main quests, along with some small suggestions for cultivation. This should help everyone make better use of them during the main story, embarking on a smooth sailing journey.
