Specter

Specter is a consumable Gear item. When used, it summons an AI-Controlled Specter that will fight alongside a player for the duration of a mission, where they can use their powers and weapons against enemies.

Tenno Specters
Tenno Specters can act as allies or enemies depending on its usage. As equipment, Specters are AI-Controlled Tenno with customizable load-outs which can be summoned during regular Missions except Archwing; As enemies, Specters serve as guardians of a Clan's Solar Rail which contesting Clans have to face during a Solar Rail Conflict, in that case these specters are known as Specter Regiment as a whole. A Specter Regiment can be created through researching it in the Clan Dojo's Orokin Lab.

Bugs

 * Telling a specter to hold position may cause the specter to act strangely, including freezing in a animation or tracking but not firing upon enemies. Telling them to follow you and re-hold position can fix the issue temporarily.
 * Currently, Cephalon Suda's Specter Blueprints do NOT drop from their death squads for unknown reasons.
