The specialties were chosen by the user, on the add an advance form, right?

Here's another piece of code from the skeleton files:

    <!-- Each skill point that is allocated by the user costs 2 CP -->
    <eval index="2" phase="Traits" priority="10000">
      <before name="Calc resLeft"/>
      <after name="Bound trtUser"/><![CDATA[
      ~if this skill is not added directly to the hero (i.e. an advance), skip it entirely
      doneif (origin.ishero = 0)

      ~adjust the resource appropriately
      hero.child[resCP].field[resSpent].value += field[trtUser].value * 2
      ]]></eval>
