You seek to live your life freely, unburdened by excessive material possessions.
Prerequisite: Chaotic alignment.
Benefit: The weight of any gear you carry is considered double for the purposes of determining your load. For example, a half-elf with a Strength of 10 and 30 pounds of gear is treated as carrying 60 pounds, which is a medium load. In addition, any armor check penalties you have are also doubled (or tripled, in the case of making a Swim check).
