"What is a prime spell?" Damian asked, his curiosity piqued.
"Something only a blood harvester can use," Steelweaver replied.
"And what is that?" Sam asked.
"A unique spell crafting skill that few earn. Spell creations made by using a large quantity of fresh, mana-potent blood. The quality and power of the spell depend on the individual or monster's blood used." Steelweaver answered.
"You mean like having an ability to control someone else's mana?" Damian asked. Sam's amused face had changed to a serious one after hearing something so fucked up.
"No, it doesn't work like that. It's more like using the mana residing in one's blood after killing him, a skill that somehow keeps the blood flowing till all the mana of the body is spent. It was not something anyone could do; only highly skilled and powerful individuals could unlock the skill through ascension. The runesmiths who could do that were even more rare."
