The Blades of Athena were chained weapons bestowed by Athena that function similar to the Blades of Chaos. They are the second pair of blades Kratos wields in the God of War series.
Also known as “Athena’s Blades”, these weapons are seemingly identical to the Blades of Chaos when Kratos first receives them in God of War (not chronologically). At the very end of God of War, they have the same abilities as the Blades of Chaos, though in both Ghost of Sparta and God of War II, their in-game attacks are changed. Given to Kratos by Athena after he killed the former God of War, Ares, these are Kratos’ main weapons during (and even after) his reign as a God.
While Kratos is a god, Athena’s Blades give off a yellow aura and are gold in colour with Blue-colored Glyphs due to the godly magic emanating from them. After Kratos drains the remainder of his godly powers into the Blade of Olympus, they revert to their basic form with a steel color and a faint yellow aura. They are then leveled up much like the Blades of Chaos and gradually regain their gold color. At level 5, they emit a red flaming glow and the glyphs become red in colour. One can obtain this gold aura and blue glyphs again when they use the God of War Armour or the General Kratos (Costume). Kratos still has these weapons at the beginning of God of War III. When available to him, they maintain the same combos from God of War II. However, when Kratos falls into the River Styx, the blades are destroyed and rusted by the souls that attack Kratos and drain him of his power.
Afterward, the spirit of Athena takes the ruined blades and transforms them into the Blades of Exile.During Bonus playthrough, if Aphrodite’s Garter is activated, the Blades of Athena are kept for use throughout God of War III. The most drastic change is that the Blades of Athena do less damage than fully upgraded Blades of Exile, but more obvious is that Kratos cannot use the grapple move, and instead of Army of Sparta, uses Divine Reckoning as his magic.In the PSP game Soulcalibur: Broken Destiny, Kratos uses the Blades of Athena, although they are known as the Blades of Chaos there. The Blades of Athena also reappear as the main weapon of Kratos in Ghost of Sparta, maintaining the godly design from God of War II. However, its moveset are a combination from the Blades of Athena in God of War II and the Blades of Exile of God of War III.
