LostSoul
Adventurer
Note: this whole fun adventure hook is spoiled with Comprehend Languages and such spells. Such is D&D. (You might be able to cheese your way out of this by saying the book has some kind of anti-magic spell done on it...)
You introduce an important literary work to the PCs. Something lost to time, written in an ancient language, undecipherable to all. This ancient book becomes important, and the PCs must translate it before the sky falls.
Set the Decipher Script DC really high, so high that Taking 20 won't make it. Then you can introduce things to the game:
-a Hag that can brew potions of Intellect, or has the needed ingredients so your wizard can brew his own potion.
-various scrolls and parchments that can be translated, adding small bonuses to the Decipher Script roll.
-finally, you can introduce a "rosetta stone" that give a big bonus to the Decipher Script roll. All these things together (or maybe most of them) plus Taking 20 adds up to the Decipher Script DC.
That's more fun than a single roll or a single spell.
