I can't imagine that this question hasn't been asked, but I can't find a straight answer. Is the slayer property supposed to affect necromancy spells? Currently, my demon Slayer Necro book is boosting my magery spells, and not my necro spells. Similarly, my Blood Elemental Slayer Mage book boosts my magery damage, and not my necro damage. So, does slayer affect Necro, and for that matter Mysticism?
