Dimwhit said:And I claim that a feat doesn't grant anything. It's simply the name given to an ability that is gained as a character levels, provided that character qualifies for the feat. It's like saying a Level grants more hit points, etc. A level is just a way of measuring a character's power and experience. It is nothing in and of itself. Feats are the same.
You could say the same thing about ability scores and hit points, couldn't you? That they are nothing but an abstraction representing the character's competence in a particular area of expertise. Ability scores represent the ability to engage in different kinds of mental and physical activities, hit points to avoid harm in combat situations (which are also highly abstract) and so on. Spell slots too; they are just a mechanic for book-keeping. But then you could say that combat, magic, and all other mental and physical activities are just abstractions and book-keeping aids, not real in themselves, ...
Where do you stop? If for any element of the game you could say that it is nothing in itself, then the content of the rules-set is completely vacuous, and you would have no reason to bother arguing about it.
If, on the other hand, there are game elements which are basic, real, and irreducible, what are they? And if feats can be understood in terms of these basic elements, are they not themselves also real?
Neither alternative is particularly appealing; it seems to be a genuine dilemma.
