Strife deck

In null/help weapons are inserted into something called a Strife Deck, which allows the person to use the said weapon in a way as you would normally use a weapon. Each Strife Deck is contained within a Strife Specibus, which in the case of multiple of these is stored 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.
