The Chains of Hades, an armament inspired by the god, acts as a ranged melee weapon. You can swing it three times consecutively to stack damage on your enemy.
Defeat Hades in Fortnite to get Chains of Hades, Hades' Harbinger SMG, and a Fortnite Aspect of the Gods for various challenges.
For the best chance to use Chains of Hades on an Olympian Boss, head southeast to Grim Gate and face Cerberus.
