Aid the Underduke Walkthrough

• While exploring Rivington, you find a group of guild men fighting Stonelord's men at the riverbank (X:-212, Y:87), you can pick a side or stay neutral. But there's an undercover harper in the team guild and you can find tadpoles on Stonelord's men (X-215, Y132), which makes helping the guild more rewarding. More tadpoles can be found in the central storage on the boat (X:-214, Y:131) and in a barrel (X:-255, Y:107). (Which side you pick makes no impact on the quest.)
• At Sharess' Caress, you can overhear two drunken men talking about Nine-fingers (Perception DC 15). You can then persuade them to talk more about the guide.

You can open the entrance by lockpicking (DC 20), if you have Jaheira on the team, select "Careful, that's the High Harper Jaheira you're speaking to" grants you access. Or, you can use Persuasion, Deception, or Intimidation skills.
•  
  (Alternatively, collect the 'Guild Ring' from the house opposite the entrance (it's in a chest). Insert it into the wall slot to reveal the entrance.)
• Talk to Nine-Fingers in her office and learn that she has laid a trap to deal with that Stonelord, but won't tell you the details. Luckily 2 drunken guild members let slip that Nine-Fingers plans to ambush Minsc at City's Counting House. You can also find the details of the plan from Uktar (near X-30, Y754) by choosing "The Quicker I deal with the Stone Lord, the quicker Nine-Fingers gets back to business". The note in Keene's room also gives away her plan.
  
  
• Travel to the Counting House Bank, and ask Head Clerk Meadhoney to permit you to enter the vault. (You can use Persuasion, Intimidation, Deception skills or by having Jaheira with you.)
  
  
• You can find the bank pass and the code by sneaking upstairs, the pass can be found  on a side table in the corner of the first room (X-103, Y-185), the code (1356) to the High-security vault is hidden in a book in the second room.

• When you reach the end of the Vault, use Water + Lightning to disable the gate to the lower level. Or you can use the code (1356) hidden in a book on the second floor.
  
  
• You find Minsc robbing the vault along with some Bhaalist Shapeshifters. Defeat the Bhaalists, on one of the Bhaalists, you will find the note mentioning Minsc's hideout is in the Sewers. (Succeed in perception checks and you can find the muddy footprints in the Vault, which also leads to the sewer.)
