Seems like this should be a trivial of 436 because it uses Charta Arcanum and it seems like it should be combinable in a Hybrid Reserach Kit or a Spell Binding Kit because it's not a tome, it's a spell. If it's a spell, it should be combinable by Beastlords, Enchanters, Magicians, Necromancers, Paladins, Rangers, Shadowknights or Wizards.
Not confirmed - just knowing what I know about spell research, it's what makes sense. Magelo has collected this as a spell research kit at 436.
