In Assassin's Creed Odyssey, what is the name of the spear wielded by Kassandra and Alexios?

In Assassin's Creed Odyssey, Kassandra and Alexios wield the Spear of Leonidas.

The weapon is a broken spearhead associated with Leonidas I, the Spartan king who led the Greek force at the Battle of Thermopylae in 480 BCE. It is not used as a conventional full spear; instead, it serves as an ancient Isu artifact with special abilities and as a key part of the protagonist's progression.

The player chooses either Kassandra or Alexios as the playable character, but both options use the same family artifact. Kassandra is the canonical protagonist in later franchise material, while the game itself allows the player to select either sibling.

The spear is different from the Dagger of Darius, a weapon connected to an Assassin precursor in the story. Odyssey is set during the Peloponnesian War, centuries before the formal Assassin Brotherhood exists.
