Stuck with riddle

Question about the riddle
I fgured out the number with math... SPOILER ALERT















8.75... however nobody in my part has int higher than 15 does that mean I am doomed to not getting the correct answer?

Yes. Yes it does. Try 'fox's cunning' - that will also allow you to speak to the Spider Queen and other folk who don't speak common, if you don't have anyone in the party with a racial knowledge of languages. I had to do that with my current play-through - a 3pc party of humans, cleric - ranger - rogue, so no-one with racial abilities and no (other) need for a high Int score. I had to do the violent quests to get Robin to a high enough level to learn Fox's Cunning to do most of the non-violent quests.
