Athens or Sparta AC Odyssey Choice and Faction Guide

The epic historical backdrop of Assassin's Creed Odyssey places players directly into the chaotic events of the Peloponnesian War. As a mercenary character, either Kassandra or Alexios, you are constantly caught between the opposing forces of democratic Athens and militaristic Sparta. Navigating this grand conflict requires a solid understanding of how faction loyalty works and how your choices impact the surrounding world.

The Illusion of Permanent Faction Loyalty

Many players assume that they must ultimately choose one side to win the entire war as they progress through the game. However, the narrative is built around your identity as a mercenary, meaning you are never permanently locked into a single faction. You can fight for Athens in one region and immediately switch to defending Sparta in the next without facing narrative penalties.

This unique freedom allows you to manipulate the geopolitical landscape solely for your personal benefit. Because the war itself is a shifting framing device, neither side can completely conquer the entire map before the story concludes. Your primary focus should be on gathering rewards and expanding your influence across the shifting territories.

How Conquest Battles Shape the World

To engage in the struggle between these two superpowers, you must actively destabilize a region by lowering its current nation power. This is achieved by burning war supplies, pillaging national treasuries, and eliminating local leaders or polemarchs. Once the territory is sufficiently weakened, a high-stakes conquest battle becomes available on your map.

When entering these battlegrounds, you are presented with a clear choice to support either the attacking or defending army. Siding with the attacking faction is generally more difficult but offers significantly better gear and experience rewards. Defending a region is typically easier to manage but yields fewer materials for your efforts.

Strategic Farming and Loot Optimization

Smart players treat the ongoing war as a highly efficient resource engine rather than a strict moral dilemma. By constantly flipping control of a region back and forth, you can repeatedly trigger profitable conquest battles. This strategy allows you to farm epic equipment and rare crafting materials at an accelerated pace.

Furthermore, specific quests throughout your journey will require you to collect items like Spartan or Athenian seals. Maintaining a fluid relationship with both factions ensures you can access guarded forts and gather these quest items with minimal friction. Balancing your gameplay this way ensures your mercenary always remains well-funded and properly equipped.
