There were only six Rare books in the library in Vampire City and one unique Rare spellbook, Epic. Evan had never before encountered a weapon or spellbook of this level. This was new to him, and he wanted to see how useful this spell was.
But, first, Evan decided to read all the Rare spellbooks, and choose one spell for his own use. He wanted to understand better how blood magic worked, and for that, he needed practice. Moreover, even among the Rarity - Uncommon spells, there were many exciting specimens. Evan was sure that higher rarity spells would only get better.
One of the Rare spells was a Creation Magic spell called - "Bloody Wall of Wounds."
This spell was a high wall of blood, on the back of which there were many bloody spikes. This spell was very useful if a mage was facing a lot of not, particularly strong opponents. They would die being put on the spikes. But, this spell worked pretty well against larger and stronger opponents as well.
