Strife Deck

In the Homestuck Universe weapons can be placed into a Strife Deck, which allows the player to use objects to Aggrieve enemies. Each Strife Deck is contained with a Strife Specibus and a character with multiple Strife Specibi will store them within a Strife Portfolio. In order for an artifact to be allocated to a Strife Deck, it must be the same kind of item as the character's chosen Kind Abstratus, and there must be a free Captchalogue Card in the Strife Deck. It appears that Strife Decks might use a special type of Captchalogue Card. Each Strife Specibus appears to come with one card in its deck by default, though it is possible to obtain and use multiple cards.

Kid's Kind Abstrata

 * Rick Smalle has, thus far, only used the wireKind abstrata, in which he had originally placed his Headphones. According to this post, Rick was unsure which abstrata to use, but realized at the start of Homebound which abstrata would be most appropriate. Rick also originally didn't think something along the lines of a Strife Specibus would ever be of use to him, as Rick's Mom was too afraid of him to strife with him. Asphyxiate might be a wireKind-only attack.
 * Lily Vivaci uses
 * Gear Ratchet uses
 * Lisa Alanan uses LanceKind abstrata. She already knows all the techinques with the Lance thanks to training during freetime before Homebound started. For more information, go here.
