A player in my group plays an evil cleric/dread necromancer. He now gets Advanced Learning. It says in the dread necromancer class description:
The spell must be a cleric or wizard spell of the necromancy school[...]
My PC has chosen a dual-school spell (abjuration/necromancy) and asked me, if that's okay. Honestly, I can't find anything about that in the rules - neither confirming nor denying. The only thing I found is in the PHB 2:
Effects that prevent a spellcaster from accessing one school of a dual-school spell prevent all access to that spell. For example, a specialist wizard cannot learn a dual-school spell if either of the spell’s schools is one of his prohibited schools.
But the dread necromancer doesn't have prohibited schools. So, can he take dual-school spells as long one of the schools is necromancy?
