Like standard Chaos Weapons, the Chaos Blade will grant a Damage Bonus that will scale with your Humanity level (up to 10), however the Chaos Blade is scaled with Physical not Fire damage.

While the base level values do not seem very strong, if you have 10 Humanity and 50 Dexterity, the weapon deals 455 Damage. However, the weapon will also inflict a percentage of damage to the player when the blade connects with an enemy. Backstabs are exempt from this.

The Chaos Blade suits Dexterity focus player builds with its strong scaling bonus.

Construction and Upgrade

While any Normal +10 Katana can be converted into the Chaos Blade, the Iaito is a better choice than an Uchigatana and much cheaper than the Washing Pole.

The Chaos Blade can be upgraded with Demon Titanite by the Giant Blacksmith to +5. A full upgrade will cost 50,000 Souls and 10x Demon Titanite. Each upgrade step will increase the physical damage and a slight bump to the scaling bonus.
