Let's say A is a ranged attack, B is a ranged touch, and C is an attack with a ranged weapon. C is an A, and B is an A. That does not mean B is a C.
All ranged attacked
must be made with a ranged (or thrown) weapon - see my earlier PHB and RC references. Essentially they are the same thing since also all attacks with ranged (or thrown) weapons are ranged attacks.
Example: Sneak attacks cause extra damage to foes who cannot defend themselves. Flat-footed characters lose their Dex bonus to defend themselves and can be sneak attacked. Flanked characters also can be sneak attacked. Therefore, they must be unable to defend themselves. Invalid conclusion: characters who are flanked lose their Dex bonus to AC.
If that sounds far-fetched, there was a virtually identical thread recently about being prone.
False premise.
Both this argument and the one in the thread on being prone assumes that the defining statement for when a rogue can make a sneak attack is when an opponent is unable to defend himself effectively. When in fact the definition is for only 2 conditions:
(1) When the opponent is denied a Dex bonus to AC
(2) When the rogue flanks the opponent.
If a rogue can catch an opponent when he is unable to defend himself effectively from her attack, she can strike a vital spot for extra damage.
The rogue’s attack deals extra damage any time her target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the rogue flanks her target.
Now if one looks at the text in Complete Adventurer..
Under Ninja's Sudden Strike (pg 8)
If a ninja cna catch an opponent when he is unable to defend himself effectively from her attack, she can strike a vital spot for extra damage. Whenever a ninja's target is denied a Dexterity bonus to Armor Class (whether the target actually has a Dexterity bonus or not), the ninja deals. . .
So since we have 2 definitions of when an opponent is
unable to defend himself effectively from an attack.
(1) When they are denied a Dex Bonus to AC or when the attacker flanks the target (from the rogue class ability)
(2) When they are denied a Dex Bonus to AC (from the ninja class ability)
Which is the correct one?
The intro statement on the opponent not being able to effectivel defend themself is the lead in to the specific conditions that the ability applies in relation to each of the two class' abilities and these conditions are different.
