Command Code

Command Code (指令紋章(コマンドコード)), also known as Command Crest is a new type of Card-Item that is meant to be engraved into any Servant's Command Cards. The method to obtain this new card-item is similar to Status Up Cards, either through Friend Point Summon or Da Vinci's Workshop, or even through Time-Limited Events or Campaigns.

By engraving such card-item into a Command Card, that particular Command Card will gain new effects, such as Heal an Unknown Amount of HP upon attacking using that Command Card. This also means that this system treats each Command Card as a distinct card.
