In Destiny, Infusion is an Armor Upgrade that can be found on exclusively helmets, but for any class. Armor in Destiny pull upgrades from specific pools, with a few Legendary and Exotic Armors being the exception. Examples of exotics with Infusion are Mask of the Third Man, Apotheosis Veil, Light Beyond Nemesis, and quite a few others. Currently one of the most useful tools in the Crota's End raid.
