The game Rolls a 6 sided dice and adds your INT score to it. Having read "Fairy Riddles" adds +2 to the roll. Having read "Fairy Vaults" adds +3 to the roll. Having the Meticulous Trait adds +2.
Your combined score has to be 15 or above to be able to translate it. I'm guessing you had a higher INT score in the previous playthrough. You can try equipping some Aquamarine or Sapphire Amulets and maybe drinking a Raven's Wisdom Potion that increases INT by 2 points for a short while.
