Assassin’s Creed Odyssey Naval Upgrade Resource Requirements: Cost Guide

Assassin’s Creed Odyssey immerses players in the vast and treacherous waters of the Aegean Sea, where naval combat is not just a side activity but a core pillar of the gameplay experience. The Adrestia, the protagonist’s trusted ship, serves as a mobile base, a key tool for exploration, and a formidable weapon against the might of the Athenian and Peloponnesian fleets. However, transforming this humble vessel into a legendary warship capable of taking on the most dangerous naval threats requires a significant investment of time and resources. This guide provides a detailed breakdown of the resource requirements and costs for fully upgrading the Adrestia, offering a strategic roadmap for aspiring Greek admirals.

The Four Pillars of Naval Power

The Adrestia’s upgrades are divided into four distinct categories, each enhancing a specific aspect of the ship's performance. Understanding what each category offers is crucial for prioritizing your resource gathering.

Hull: This upgrade path directly increases the ship's health and armor. A stronger hull allows you to withstand more ramming damage and enemy arrow fire, which is essential for surviving prolonged battles against multiple triremes or the legendary mythical ships.
Ramming: This upgrade enhances the damage dealt by your ship's ramming attack. A powerful ram is one of the most effective ways to quickly sink enemy vessels, especially when combined with a well-timed brace to counter their attacks.
Arrows: This category improves the damage output of your lieutenant archers. These volleys are your primary source of ranged damage and are excellent for whittling down enemy health before moving in for a ram or boarding action.
Javelins: This upgrade increases the damage of your javelin throws. Javelins have a shorter range than arrows but deal significantly more damage per hit. They are perfect for targeting specific weak points on enemy ships once you close the distance.

Each category has five tiers of upgrades: Base, Bronze, Silver, Gold, and Legendary.

The Currency of Conquest: Understanding Resources

Upgrading the Adrestia requires two primary types of resources: Drachmae (the game's currency) and Crafting Materials.

Drachmae: Acquired from completing quests, selling unused gear, looting treasure chests, and winning naval battles.
Crafting Materials: These are further subdivided into three types:
- Wood: The most common material, used in every single upgrade. Found by looting naval supplies (floating crates in the sea), cleaving ships in half after battle, raiding military camps, and breaking various objects like crates and bows in the world.
- Leather: A moderately common material, required for most upgrades. Gained primarily by hunting wildlife (deer, boars, lions, etc.), looting from soldiers, and cleaving ships.
- Metal: The rarest of the three base materials, essential for higher-tier upgrades. Obtained by dismantling unused weapons and armor, mining ore deposits (shiny rocks found throughout the world), and looting from nation chests in conquered forts.

Additionally, a fourth, unique resource is required for the final Legendary tier of each upgrade:

Ancient Tablets: These are rare items found in ancient ruins, large tombs, and certain legendary chests scattered across Greece. They are also sometimes rewarded for completing specific story missions. You will need a total of 10 Ancient Tablets to complete all four Legendary ship upgrades.

Note: The final Legendary upgrade for each category costs 2 tablets, but the in-game menu may show a requirement of "1/2," meaning you need two per category, for a true total of 8.

Efficient Farming Strategies

Amassing this fortune requires a focused approach. Here’s how to do it efficiently:

Loot Everything: Never pass by a floating crate in the sea. They almost always contain wood and sometimes leather. On land, smash every crate, vase, and rack you see.
Cleave, Don't Just Sink: After winning a naval battle, always choose to "Cleave" the enemy ship instead of just sinking it or boarding it. Cleaving guarantees a large bounty of wood, leather, and some metal.
Raid Forts and Camps: Military locations are treasure troves. Nation chests provide metal and drachmae, while regular chests and lootable objects offer a mix of all resources. Use Ikaros to tag all lootable objects before entering.
Hunt and Dismantle: Regularly go on hunting trips in regions like Phokis, Arkadia, and Makedonia. Dismantle all grey, blue, and even purple gear you don’t need instead of selling it; this is a primary source of metal. Sell epic and legendary gear for drachmae instead.
Explore Tombs and Ruins: Make it a habit to seek out and fully explore every ancient tomb you find. Not only do they provide ability points, but they also often contain an Ancient Tablet and other valuable loot.
Conquest Battles: Participating in these large-scale battles yields substantial drachmae and resources upon completion. Choose the attacking side for a potentially larger reward.

Conclusion

The journey to a fully upgraded Adrestia is a long but incredibly rewarding one. The staggering resource requirements are a testament to the scale of Assassin’s Creed Odyssey. By understanding the costs involved and implementing efficient farming strategies, you can systematically conquer the Aegean Sea. The moment you unleash a full volley of legendary javelins and watch a Athenian trireme explode into splinters, you’ll know every hour spent gathering wood and metal was worth it. Your legendary ship awaits, Misthios. Set sail and claim your destiny.
