History of Funeral Pyre

Funeral Pyre is the Exotic Ace of Spades Catalyst perk for the Ace of Spades, a Hand Cannon. It boosts the Firefly trait so that, while Memento Mori is active, Firefly deals more damage, which makes it easier to clear groups of enemies in a short time.

Acquisition

The perk is unlocked by upgrading the Ace of Spades Catalyst. The Catalyst is a rare random drop from Strikes and Crucible matches, and unlocking the perk requires 500 kills with Ace of Spades.

The Ace of Spades itself is purchased from the Exotic Archive at the Monument to Lost Lights.
