Patryn of Elvenshae said:A prerequisite is not an effect
I am afraid that here is one of the main points I see your arguement breaking down.
This part simply makes no sense. It isnt necissary for the prereq to count as an effect, it is part of the feat. The only thing that matters is whether or not the 'feat' which the prereq is 'part of' counts as an effect, and I have shown that the rules do indeed count feats as effects.
As for the other example, which I believe was alignment descriptors, those only work for natural weapons as well. It is 'exactly' the same thing, just written in a slightly different format.
To me, to say that one works while the other does not is to be ignoring the rules of the game.
The feat requires a natural weapon on which to impart its effect, which is itself, and the monks unarmed strikes count as a natural weapon for that effect. So it works.
I feel that you are trying to draw lines that not only do not exist, they simply 'cannot' exist in a logical fashion.
