Type: Katana

Rank: S

Quantity: One

Description: Looks like an ordinary Katana made of steel. The handle is made out of silver and wrapped with leather.

Abilities: This sword Loves to drink blood, the more blood, the more power. It becomes more powerful everytime it "drinks" blood.

History: This sword was given to Zeref from his father. It is said that it was handmade from the Netherworld, being smithed by the most skilled blacksmith with the fires of Hell.

The description is to explain what the katana is made out of.

As for blood power up, you'll have to explain just how much blood increases your "power" by how much. You will also have to explain just what this "power" is to you. In the past this was done through a complex formula for quarts of blood to power, though I don't remember how they defined power.

It cannot have the ability to cut through anything.

Jutsu is plural. The blood drinking ability is free with this weapon and clan, but this part will cost you. If that is acceptable, then leave it as it is. If not, then take it out.

how much would it cost?

Well, this is an S rank Weapon, so;
Or what about some equipment? Equipment prices are:

D: 5,000 - 50,000
C: 55,000 - 150,000
B: 170,000 - 1,000,000
A: 1,200,000 - 2,000,000
S: 2,200,000 - 4,000,000

#Yaoming face.

What abilities?

Now that you only have the clan ability, the weapon will be free. You still need to describe what it is made out of in the description.
