Ghost shell

Ghost Shells are aesthetic modifications to a Guardian's Ghost. During Year One of Destiny, Ghost Shells were a purely cosmetic item and only two were available to players (Generalist and Frontier). Beginning with Year Two, they will feature Defense, Intellect, Discipline, Strength, and Light stats, as well as perks that aid in the discovery of Planetary Materials and increase Glimmer rewards during combat.

Trivia

 * Before Year Two, Destiny game files mentioned a number of Ghost Shells aside from Generalist and Frontier which were never made available to players. These include the Consensus Shell, Foundry Shell, Intrusion Shell, Shipwright Shell, and Vanguard Shell. It is unknown if these shells will be obtainable in Year Two.
