If he has 15 drops of Mythical Beast's blood, he would never trade it with such a suspicious item.
Those 15 drops can be made into 15 Legendary-Grade Items if the Magic Craftsman has decent crafting skills! It can also create the best auxiliary parts of his Diamond-Tier Automatons if handled by the Magic Technicians.
Aside from that, there is also an item that can summon a Mythical Beast Projection with a drop of blood, and it's probably the best option out there when getting a drop of their blood.
After all, Mythical Beasts are known for their power and mysterious powers.
It is just too wasteful to trade 15 drops of Mythical Beast's blood for a necklace with unsure origin. Vincent couldn't think of anyone that would take such a deal except for him.
"Do you know why Sir Lockwell needed this much blood?" Vincent asked. He also knows well how important the blood of a Mythical Beast was.
If possible, he would offer several Peak-Grade Potions instead to get this necklace.
