The oracle that knows a guy that actually knows the answer

Oracles always seem to know stuff, but give so vague answers, you just leave them wishing you'd punch them instead.

So instead of having the oracle give open-ended answers, make them always answer with a name of someone who knows.

And not like, "Oh you wish to know where the lost treasures of the reptilian conquerors are? You should ask a man with a hat about that", but rather, "Oh you wish to know where the lost treasures of the reptilian conquerors are? You should ask Johann van der Bajskorv the Third."

This person MUST know the answer, otherwise this whole thing falls apart. But there's nothing saying that they are willing to tell the answer, or are even alive.

And remember: these oracles always just answers with specific names, e.g. not where they are. That requires another question - which will be answered with...another name.

"But where can we find Johann van der Bajskorv the Third?"

"Oh you wish to know where to find Johann van der Bajskorv the Third? You should ask Little Unwin Binwin Simsalabim."

And so on.

Try it! I haven't!

and hanging around his neck, "an ultra-magic" necklace (his own words).
