i cant get any info on wimboll the story says "head uptown to deal with wimboll" and if i got up there the only option related to him is "gather information about wimboll" i checked the wiki and it says to use cunning potion but that dose ot work.
The cunning potion is just to get in. You probably already found the ledger, see if it’s in your inventory. You probably just were clicking through quickly and missed it, but when you find the ledger the game tells you that you need to take it to Carol. Then after that you’ll go back and confront Wimbol in person.
