In Assassin's Creed Odyssey, what legendary weapon does the protagonist carry?

In Assassin's Creed Odyssey, the protagonist carries the Spear of Leonidas.

The weapon is the broken spear once associated with Leonidas I, the Spartan king who appears in the game's 480 BCE prologue. Kassandra or Alexios inherits it through their family line, and it becomes a defining gameplay and story object during the Peloponnesian War campaign.

The Spear of Leonidas is not used as an ordinary complete spear. Its fragments provide the protagonist with powerful abilities and are upgraded as the story progresses. The weapon also links the historical Spartan opening to the game's wider mythology involving the Isu and ancient artifacts.

Players can choose either Kassandra or Alexios as the playable character, but the spear remains the same named relic in both versions. This makes it different from the protagonist's regular swords, bows, and other interchangeable equipment. The game's title refers to Odyssey's Greek setting and journey, while the spear supplies a direct connection to Leonidas and the earlier battle at Thermopylae.
