List of Contents
To initiate this Act 3 side quest, go to Sharess' Caress in Wyrm's Rock Fortress and talk to Earspoon near the lobby in the first floor.
You'll need to convince them to spill the beans about a certain Nine-Fingers and the location of the Guild Hall.

Go to the Guild Hall which is located northeast of the Heapside Strand waypoint. You'll be stopped by a guard and you'll have to do some successful skill checks so he'll let you through.
Once inside, head northwest, past the Guild Hall Bar, and into Nine-Fingers' Office. She will ask you to bring Jaheira and they'll talk about setting up an ambush on the Stone Lord.
If you don't have Jaheira recruited, you can go directly to the Counting House to face the Stone Lord, and continue the quest from there.
Jaheira Companion Guide: How to Unlock
Nine-Fingers will refuse to discuss further about the ambush, so head towards the Guild Hall entrance until you find a Halfling and a Gnome. Convince them to tell you about the details of the ambush.
They'll point you towards the Counting House, located at the southern area of the Lower City.
When you arrive at the Counting House, talk to Head Clerk Meadhoney behind the counter. You'll need to talk your way through so he'll grant you a temporary vault pass.
Open the iron fence in the middle of the Counting House and head down into the vaults.
You'll eventually encounter a locked vault with a puzzle mechanism to open it. Step on the four tiles in the order shown above to unlock the vault.
Before you proceed into the passageway, get ready for a fight and prepare some See Invisibility spells if available.
After you enter the passageway, you'll meet the Stone Lord and some cultists who stole all the gold. The Stone Lord and the doppelganger of Jaheira will escape, leaving you to fight the cultists.
The cultists will turn invisible and hopefully your See Invisibility will reveal them. If not, you can use AoE spells to knock them out of it, as long as you have an idea of their general location.
After the fight, you can talk to Rakath Glitterbeard and offer to find the stolen gold. The stolen gold is held by one of the Stone Lord's companions hiding out in the sewers, and you'll be heading there anyway. Rakath will reward you with an Elegant Studded Leather, a very rare light armor, if you return the gold.
You can also bargain with him to split the stolen gold if you find it. If you don't touch the gold and return it to him, he'll agree to split the gold, then give you the Elegant Studded Leather inside the vault.
After the fight, you'll need to chase after the Stone Lord into the sewers. Southwest of Bloomridge Park is a manhole which you can use to go down the sewers.
Proceed to the northwest until you find the Abandoned Cistern. Get ready for a fight as some guards will prevent you from going further in.
After getting past the posted guards, you'll come upon a big contraption and some valves. Before anything else, have your characters interact with the Sluice Valve to the left of the Water Level Valve. If they pass the Athletics check, the Sluice Gate will open immediately, allowing you to skip this puzzle.
To open the Sluice Gate, you'll need to match both water and temperature levels to perfect. This puzzle requires a bit of timing, so it's recommended to do this puzzle with a single character and avoid getting blocked by your allies.
Head inside the tunnel and get ready for another fight.
When you reach the end of the tunnel, you'll find Minsc, Jaheira's doppelganger, and some Zhentarim. You'll need fight your way through out of the chokepoint and move to a more favorable position.
Try to knock-out Minsc instead of outright killing him, or else you cannot recruit him as a companion and Jaheira will leave permanently. You can toggle non-lethal attacks in the Passives tab below the skills bar. If you have Jaheira recruited, you can spare Minsc from the Emperor and recruit him. Read the note from the corpse of Jaheira's doppelganger and return to the Guild Hall.
One of the enemies you'll encounter in the fight is the Zhentarim agent Roah. You'll need to kill her to get the stolen gold back. If Roah isn't among the enemies, the stolen gold could be with Boss Friol instead.
When you arrive at the Guild Hall, the Zhentarim will be trying to take over the Guild Hall. Eliminate them and try to ensure that Nine-Fingers lives.
Speak to Nine-Fingers when the hostiles have been eliminated to finish the side quest, then she and the Guild will join you as allies in the final battle against the cult.
To recruit Minsc, you'll need to have Jaheira recruited as well in Act 2. If you go through the side quest without Jaheira, you'll still be able to fight Minsc but he won't join you.
In the battle in the Abandoned Cistern, you need to take down Minsc with non-lethal attacks. You can switch to non-lethal attacks by selecting the Passives tab below the skills bar.
After the battle, the Emperor will tell you to kill Minsc, but choose to save him instead. He will then go to a room in the northern side. Follow him through the hole in the wall and ask him to join you.
Minsc is a Human Ranger and can be recruited in this side quest, as long as you don't kill him and have Jaheira recruited.
Companions Guide: All Recruitable Allies
Nine-Fingers and the Guild will join you as allies in the final fight against the cult. They will be listed in the Act 3 quest Gather Your Allies.
If you return Rakath Glitterbeard's gold, he will give you they key to vault number 9, containing an Elegant Studded Leather, a very rare light armor.
