Benefit
You are a nomad of the steppes, used to traveling long distances, often on foot. You gain a +2 competence bonus on Jump checks. In addition, you do not need to make Fortitude saves when making a forced march until you have traveled for 12 hours (see Movement in Chapter 9 of the Player's Handbook). The save DC for longer travel is 10 + 1 per hour beyond 12.
