Sword of blood
Exactly as seen earlier in the castle.
The sword.
“What does that one do?” I asked, pointing to it.
“It drinks blood. For anyone it kills, their blood is stored in the blade. You would try to always have a clothing between you and the hilt”
That did not sound more beneficial than fairy dust.
“So how useful would it be to protect me?”
With only a smile, “very”
Time to close the deal.
“I have one silver coin” playing with the coins against my fingers.
“Make it three and we have a deal”
