Either found a typo or my understanding has a typo. 

On page 8 the sorcerer accumulated  Obligation through negating negative outcomes or by getting benefits. Then they roll 1d10 and if their roll is under their current obbligaton the benefactor is content. Why not immediately get a 10 Obligation and never attempt to lower it? Unless they want to trigger a quest or become corrupted. 

That aside like the class, very flavorful in a little text.
