So, on page 26 of BW where it explains graduated tests, it takes a wise skill as an example - more successes, more information on the topic.
But then in Codex, in the chapter on Wises as Information (pages 206-207), it uses a different example that kinda contradicts this:
for argument’s sake , let’s say that he did. At that point , Anthony
would have had to decide whether to simply Say Yes and give Thor
the information or call for a Dragon-wise test. Further he also had
to consider these details: Would having the answer allow Thor to
circumvent obstacles he had planned? Could he think of an interesting
consequence’ or complication that would result from a failed wise test?
[f the answer to either of those questions was “No” , he would have just
given Thor the answer: The first dragons were born from the sparks
that flew off when the world was forged upon the anvil of the Void .
If the answer to either of those questions was ‘’ Yes", Anthony would
have called for a test. He might even have fished for more details: " Do
you want the common legend that is told around hearths on stormy
nights? That’s Ob 2. Or do you want the story the dragons believe?
That’s Ob 8.
How was this not a perfect opportunity to demonstrate a graduated wise test? Like when would you use it if not in a situation like this?
Or am I misreading this and this actually is a graduated test but where GM tells the player in advance what he can learn depending on successes? Is that how graduated tests are supposed to work?
