Pergaminho Arcânico
"An aberrant sorcery, discovered along with red glintstone by those exiled to the north for their crimes. Summons large thorns from a whorl of blood shed by one's own hand in penance for sins. This sorcery can be cast repeatedly. The Academy reviles this sorcery, which draws its power from faith."
