What is the name of the ancient artifact carried by Kassandra in Assassin's Creed Odyssey?

Kassandra carries the Spear of Leonidas in Assassin's Creed Odyssey.

The spear is a broken weapon that once belonged to Leonidas I of Sparta, Kassandra's maternal grandfather. In the game, it is an Isu artifact with extraordinary properties, and its connection to Leonidas links the protagonist's family history to the wider mythology of the Assassin's Creed universe.

Kassandra uses the spear as a weapon and as a source of abilities throughout the story. Its power is gradually enhanced through upgrades, while the narrative reveals more about its origin and significance. The player can choose Alexios instead, but the canon version of the protagonist is Kassandra.

The Staff of Hermes Trismegistus belongs to later events involving Layla Hassan, and the Apple of Eden is a different type of Isu artifact that recurs across the franchise. The spear's Leonidas connection makes it specific to Odyssey's opening history and central plot.
