Thanks for the tips! Got it working.

If anyone else needs the script, here it is. (Why re-invent the wheel, right?)

      ~if we're disabled, just get out now
      doneif (activated = 0)
      
      ~add our rating to the damage of any thrown weapons
      foreach pick in hero from WeapRange where "Armory.Thrown"
        perform eachpick.field[wpDamage].modify[+,field[trtFinal].value,""]
