So it's a non-Conjuration spell that targets an object, doesn't allow SR, but deals Empowerable damage to something that isn't the target.
Scorching ray affects one or more targets, Flame Arrow affects arrows.
Scorching ray causes magical damage, Flame Arrow causes fire damage.
Scorching ray won't work on a golem, Flame Arrow likely will.
Scorching ray is a ray spell that causes an attack, Flame Arrow is a spell that simply augments an arrow.
Scorching ray allows you to cast and blast, attacking with Flame Arrow is done as per any other projectile weapon.
And is also affected by Augmentation. A more powerful version of the power results in the claws dealing more damage. Why should 'more magic' from augmentation make the damage greater, but 'more magic' from Empower not be applicable?
