So, I sat down with my scribe today to craft some necro books with mods. On my 9th book, I happened to get a repond slayer necro book. I was very excited, figuring I could wither a coon spawn even faster now. However, when tested, a necro spell book only adds spell damage increase to magery spells. My fireballs got a boost towards repond, but none of my necro spells. Any logic behind this?
