Phoenix Protocol

Phoenix Protocol is an Exotic chest armor piece for Warlocks, introduced with Destiny 2: Forsaken.

Overview

Its exotic perk is Battle-Hearth: kills and assists made while standing in your Well of Radiance return Super energy. Per one source, the first kill gives 10% Super energy and each later kill gives 1.5% less, with a floor of 4%. It suits stationary encounters with waves of enemies, such as the Blind Well, rather than boss damage phases. The flavor text is a Warlock-themed lore note about stars dying and renewing.

Acquisition

• Exotic engrams, the most common source.
• Extremely rare world drops.
• Xûr, who sells rotating Exotics for Legendary Shards when this piece is in his stock.
• Engram focusing with Master Rahool in the Tower (Exotic Armor Focusing, per the item's game data).

Sources describe the engram and Xûr routes as they stood at the time of writing; check Xûr's current stock before relying on it.
