What sort of difference? A claw is a valid target for Magic Weapon, but the spell cannot be cast on it.
-Hyp.
Maybe my days of MTG are messing me up; there, if you didn't have a valid target, you couldn't cast the spell. In D&D you can always cast the spell, but the spell fizzles if you don't have a valid target. And the extra line in the text of MW doesn't change it.
Is this correct?
@FireLance: I don't think we need to get into the racial prerequisite stuff to solve this problem. I have a different worry:
My main concern revolves around "prevenience"- the notion that an effect can precede its cause. I understand that prerequisites are around before their associated feats; that's what the
prerequisite means. But I don't like the notion that an effect enhancing a natural weapon could be around before the feat that provides the effect is around.
I was under the impression that targetting took place before a spell had its effects; that targetting was a prevenient phenomenon. Hypersmurf has quoted a rule to the effect that this is mistaken. So it seems that only prerequisites are prevenient.
If the enhancement from INA is going to make the monk's unarmed attack count as a natural weapon, it has to do it at the time when the prerequisites are satisfied, which is before the feat is taken. To do this, the enhancement effect would have to be prevenient. I can't see how this is possible.
Let me ask a question: In your opinion does a 3rd level monk meet the natural weapon prerequisite of INA? He hasn't multiclassed, so his BAB is only +2; he *doesn't* meet the BAB prerequisite. But does he meet the natural weapon prerequisite?
I would immediately answer no. If his unarmed attack counts as a natural weapon for the purpose of the INA feat at level 3, then that means that, somehow, the INA feat is enhancing his weapon even though he isn't going to take it for another 3 levels. Is this monk therefore doing damage as a monk one size category larger because of the feat that he someday might take? I certainly hope not!
Now, I proposed a principle that when X counts as Y for the purpose of effects, it counts as Y for the purpose of prerequisites. I call it the principle of prerequisite conversion. I think it is a sensible rule, and it allows INA to be taken by human monks. I just think it is an addition to the rules, not implied by them.
My claim is that any attempt to eliminate the distinction between prerequisites and effects runs into the prevenience problem; if there is not distinction then effects, like prerequisites, can exist prior to their associated feats. And that leads to 3rd level monks getting the benefit of a feat they haven't taken and don't yet qualify for.
If you can solve the prevenience problem for me, then you might have a convert.
