This is the term that is used to describe the size of die that is tied to a particular Trait or Specialization. This is expressed by the second number in a entry. The dice used in this game system are 4 sided, 6 sided, 8 sided, 10 sided and 12 sided. A strength of an 8 sided die would read #d8. At no point can strength be increased above a 12 sided die.
