Age of Exploration Legend: Portugal Upgrade Guide How to Upgrade Portugal in the Age of Exploration Legend

Portugal, a civilization with a glorious history of navigation, stands out in the Age of Exploration with its outstanding maritime trade and exploration capabilities. If you choose the Portuguese civilization, then you are embarking on a journey full of adventure and wealth. Today, I will bring you an upgrade strategy guide for Portugal in the Age of Exploration. As a Portuguese commander, not only do you need to search for treasures and open new sea routes, but you also need to incorporate the entire world into your control through countless trade routes.

From the very beginning, you need to set the tone for your goals—trade and exploration are Portugal's most powerful weapons. At the start of the game, you will receive the "Gate Closure" skill, which increases the vision range of all units. For every civilization you encounter, you can gain more trade routes, a true blessing for any trade enthusiast! Most importantly, each of Portugal's city-states can open its borders outward, meaning you can establish connections with almost all cities, quickly expanding your influence. Whether you are hopping between islands for exploration or interacting with enemies on land, this vision bonus from Portugal can greatly enhance your understanding of the world.

Portugal's core advantage is also reflected in its national ability, "House of India." You will be able to obtain amazing bonuses through maritime trade routes, which must originate from coastal cities. This makes it crucial to carefully select the locations for building your cities, preferably close to the coastline. Every city adjacent to the coast can provide additional output, especially as the movement range of trade routes and merchant units in water significantly increases. Although this ability has some limitations, its high bonuses can quickly lead to substantial resource accumulation. The results that can only be achieved at sea are unparalleled by any land-based civilization.

Next, let's talk about Portugal's unique unit—the Carrack. This is not just a simple naval unit; it has the same speed and combat power as a regular caravel but offers more upgrade opportunities and lower maintenance costs. Most importantly, it can build trading posts at sea. This allows you to further strengthen your trade network by building trading posts near other civilizations' cities. When you have several such ships, you can easily establish a vast commercial empire.

If you want to further consolidate your commercial advantage, then trading posts are another secret weapon. These trading posts not only bring you substantial gold and production, but they also increase the resources of the cities with which you trade. More interestingly, trading posts cannot be easily destroyed by enemies, providing you with more security when dealing with other civilizations or city-states. Although the construction conditions for trading posts are strict, requiring them to be built next to specific resources, once established, the benefits are enormous.

Talking about Portugal's unique building—the Nautical School, its function can be described as adding luster to an already splendid scene. As an alternative to the University, it not only increases the production speed of naval units but also provides additional science points through the terrain of the coastline. If you can utilize coastal resources and build nautical schools in each city, you will find that your research speed is much faster than that of other civilizations. Moreover, for every two coastal tiles, you get one science point, which puts your technological development at the forefront, giving you more strategic options.

In terms of city planning, Portugal should focus on the construction of harbors and nautical schools. Your capital and other coastal cities should be as close to the coastline as possible, with harbors and nautical schools built to accelerate scientific progress and increase the output of your cities. Additionally, the lighthouse and increased trade route capacity of the harbor can make your commercial empire more substantial. To maintain a steady flow of gold, remember to use trading posts to boost your trade revenue with other cities.

If you are interested in naval battles, Portugal's naval units are a force you cannot ignore. You can strengthen your naval power by upgrading and building more ships, especially wonders like Kilwa. Additionally, the Arsenal of Venice is a necessary facility for naval warfare. Whether you want to build a powerful navy or strike against enemies, Portugal's maritime advantages will give you the upper hand in battle.

The above is the content of the upgrade strategy guide for Portugal in the Age of Exploration. Portugal's advantages in the Age of Exploration mainly lie in maritime trade, exploration, and naval units. By reasonably utilizing trading posts, nautical schools, and carracks, you can build a powerful maritime empire, not only earning a large amount of resources but also becoming the world's economic hegemon through controlling trade routes and city-states.
