Actor attributes that are changing throughout the game. If they appear to be dublets of aspects from actor kinds, e.g. HP, they may be results of casting the dice specified in their respective actor kind and/or may be modified temporarily, but return to the original value from their respective kind over time.

Other properties of an actor, in particular its current aspects, are derived from the actor's trunk, organs and equipment. A class of the aspects, the boolean ones, are called flags. Another class are skills. Stats are a subclass that determines if particular actions are permitted for the actor (or faction).
