Mila
A soul could only accept so many contracts and that amount was determined by the strength of the contracts and the value of the Soul stat. But there was a very easy trick to make an almost unlimited amount. Just don't bind yourself.
It was relatively simple, as all you had to do was make contracts where all the terms limited only the other party, but in practice it was difficult. People would pretty much only agree to that type of contract when the alternative was death or something even worse. And, without the anchor of a second soul, the contracts were extremely easy to break for anyone with the right type of skill.
