Been a while since playing... Does Agonising Doom require a to-hit roll? Doesn't seem to from the description. In fact, from reading "The Magic Attack Roll," it seems like spells often don't have to hit, you just go straight to rolling a saving throw against a magical to-hit roll. Exceptions seem to include Telekinesis (hitting the target with the thrown object, seems like this would be a typical ranged attack), and various Ill-Fortune (where if you can't auto-hit due to eyes being averted, that you can still touch, but would have to make a touch melee attack).
