The Blueblood Sword is a Straight Sword in Demon's Souls.

Description Edit

In-Game Description

A white iron straight sword born from the soul of the demon Maiden Astraea.
The sword of true nobility, endowed with the essential power humans are born with, which increases its attack power.


The Blueblood Sword is created by giving Blacksmith Ed the Pureblood Demon's Soul, which can be created from an un-upgraded Broken Sword. As with the other Boss Soul Weapons, Blacksmith Ed must have been given the Red Hot Demon's Soul beforehand.

General InformationEdit

While it has some minimal scaling in Strength, Faith, and Magic, the Blueblood Sword unusually scales with the Luck stat. Scaling benefits start slowing at around 25-30 Luck.
