* A flaming weapon (without any note of exceptions based on weapon type)* does +1d6 points of fire damage on a successful hit.
* A successful hit is an attack roll that equals or exceeds the target's AC.
Therefore, any flaming weapon does +1d6 points of fire damage with any attack roll that equals or exceeds the target's AC.
That rule is talking about whips as whips. It isn't talking about flaming whips. "Flaming" isn't a mere adjective. It is a quality, and the rule for that quality is stated above.
Unless, somehow, a flaming whip is no longer a whip, it follows all the rules for whips.
Unless you care to rule that someone with Weapon Focus (Whip) does not get a bonus on attack rolls when using a Flaming Whip?
* Note that it doesn't need to make any exceptions based on weapon types. D&D is a system based on inheritance. If I make a new kind of Baatezu, I don't need to specify all his basic traits. All I do is note that he's an Outsider with the Lawful and Evil subtypes and the Baatezu traits, and he's covered.
Similarly, if I make a flaming whip, I don't need to specifically call out all the whip rules - they're inherited based on the fact that it's a flaming
whip and not a flaming
sword.
Consider the magic weapon creation process. In order to even make a flaming whip, you must start with a masterwork whip.
Does a masterwork whip follow all the rules for whips? Yes.
You then must enhance it with at least a +1 enhancement bonus before it can be given any special abilities at all.
Does a +1 whip follow all the rules for whips? Yes.
You may then add the flaming special ability to the +1 whip.
Does a flaming whip +1 follow all the rules for whips? Yes.
If it doesn't, why doesn't it, and where did the change occur?
