It is not that ordinary power enhancements like Arthur's have no hope or can't surprise. They can, but only in special situations when the bloodline mutates or becomes capable of growth.
But mutation and growth are difficult to achieve. And even if they happen, it will be extraordinary if they can increase to Arthur's state.
From what Elder Calcetti could sense, Arthur was gaining a +40 to his power. That's a four times increase from what Arthur was getting from his bloodline when he was the first mortal.
This realization made Elder Calcetti ask the leader, "Will this be the maximum enhancement from his bloodline, or is his bloodline capable of more growth?"
This question made the leader stop joking around. He stopped chuckling and replied solemnly, "It is possible for it to grow. It is unlikely to happen, and even if it does happen, it will be difficult, but I won't count it out from happening because when I saw him 20 years ago, the boost from his bloodline was just +30."
