  ===Attachment cards===
  Attachments are cards that are used exclusively to modify other cards. An attachment may not be in play unless it is attached to the proper type of card, typically a character card unless the attachment itself says otherwise.
  Attributes of an Attachment card consist of a gold cost (generally represented by a number overlaid on a gold coin in the upper left corner), a name across the top that may be proceeded by a black flag if the attachment is unique and/or an infinity symbol if the attachment is ''endless'', a House affiliation (represented by one or more House shields in the upper right corner, although neutral attachments will have no shield), artwork depicting the attachment in the top half of the card, and a text box in the lower half of the card. Throughout the Winter block, some cards were printed with a black crow icon in the bottom left corner to indicate the attachment is ''Doomed''. It is unknown if such attachments will appear again.
  Within the textbox may be ''traits'', ''keywords'', other game effects or icons, and flavour text from the novels. Traits are bold and italicized words at the top of the textbox, and usually represent types of enhancements, such as skills or titles. They have no game function themselves, but instead are used to group attachments together in order for other game effects to be used by or against varied groups of attachments. Keywords are game mechanics defined in the rules that affect that attachment such as Setup, which allows the attachment to be played at the beginning of the game unlike normal attachments.
  Occasionally, game effects can cause cards to become face-down attachments attached to specific other cards. These function the same as normal attachments, except they are treated as having no names, no text, no gold costs, no House affiliations, and are discarded if they are ever forced to leave play.
