Make sure that you level up Luck accordingly. The Blueblood uses Luck as a hidden stat to power up it's attack, it has an A effect to it, for each point of luck you get a 0.95 increase to it's power.
Blueblood is an extremely powerful weapon for pure Luck users, as it works as a regular Sword, which means you can do lots of attacks with small stamina drain, and each attack is really damaging ;)

For each NG+ that you start playing, the difficulty increases by 8%. There are people on NG56+ now, that means an astounding 448% increase to NG+ difficulty XD
