Having served as a mount for some time, you have grown so accustomed to the weight of a rider that you no longer even feel it.
Prerequisites: Quadrupedal, Strength 12.
Benefit: You may ignore the weight of one living creature you carry when determining your load. You still cannot carry creatures that are too large to ride you.
Special: You may take this feat multiple times; each time you do, you may ignore the weight of one other living creature you carry.
