Rats have an amazing sense of balance: they can walk along clotheslines, the moorings of ships, and narrow rooftops with amazing agility. A rodens using Absolute Balance can maintain her balance on any solid surface, including ice, he slick bottom of a riverbank, a greased surface, or a snowdrift. The best part: the rat doesn't leave tracks.
Roll Dexterity+Athletics, difficulty 6; extremely treacherous surfaces may raise the difficulty to 7 or 8. If climbing proves necessary, the rate still depends on the Dexterity+Athletics roll, but the Ratkin cannot fall for the duration of the scene. If the feat is something an ordinary rat can normally perform, no roll is necessary; this applies even if the Ratkin is in Homid or Crinos form. Some feats of balance are still impossible.
