Special Modifiers

You can also add special, thematic modifiers for certain skill uses. For instance, you might give a creature that secretes adhesive “Athletics +7 (+9 to Climb or Grab).” This special bonus should still remain at or below the extreme number, especially if it has a combat purpose like the Grab bonus above. You don't need to do this when the skill use is for the skill's primary purpose, such as “Piloting +7 (+9 to Pilot a starship).”
