Baldur's Gate II: Shadows of Amn/Irenicus' Dungeon

Setting Free Minsc and Jaheira
Now Imoen is your party is time to free some fellows who can help you. Head north and east (x 4030 y 2760) and Minsc will talk to you. Enrage him by selecting options 1,2,3,1 and he will enter your party. You get 3000 XP for that.

Now you have to free Jaheira. Go north (x 3900 y 2675) and talk to her. Agree freeing her if you want Jaheira in your party. You can't unlock the cell so you have to find the key.

Go left to the room there (x 3250 y 2850). Don't be worried with the golem. He won't attack you. The key is on the table. You also find these items: Open the chest and you'll find the following items:



Now use Imoen detect trap to open the paiting. You get a Dagger +1 and three Healing Potions. Also, if you imported your character from BG1 with the Golden Pantaloons they'll be there.

Now open the north door (x 2865 y 2815) and you'll find your first enemy, Smoke Mephit. It HP is 27 and gives you 420 exp. If you keep walking north you'll find another door, but you can't open it, so head back to the torture room and release Jaheira, receiving 3000 exp.

Finding Rielev
Go southwest. Follow the passage and you'll enter in a room with a Lightning Machine (x 2650 y 3160) which summons Lightning Mephits and shoot Lighting Bolts at you. You must deactivate the machine to stop summon Mephits. Click twice on its control panel (x 2835 y 3060) to deactivate the machine. Remember that you must be near the object to do this. You get 2000 XP for that. Note that in the next room you'll be healed, so killing Mephits is a good opportunity to gather experience (420 exp).

Continue your way and you'll find Aataqah, a genie. You can just ignore him if you want. Otherwise he give you two options: if you pick "Push the buttom" he will summon an Ogre Mage (650 exp) and you also get 3500 exp. If you pick the other option he will summon four Gibberlings and you get 3500 exp too.

Now head west (x 1450 y 2660). You will find goblins here. They're very weak, but the archers (the last two) could do big damages with the arrows. So focus on killing first the archers before attacking the others.

The passage will lead to a fork. Go left first (x 600 y 2400). You will find a Steam Mephit (420 exp) here. At the end of the room there's an Ice Mephit. There are also three containers: a crate (x 675 y 2705), a barrel (x 825 y 3045) and a trapped crate (x 1033 y 3025) where you find these items:

Now head right (x 890 y 2200). Here there you'll find a Golem and a Radiation Mephit (420 exp). Talk with the Golem pretending you're its master. Tell it to open the doors and it informs you that you need a special gem to active it. You can just pickpocket it to get the key, but you'll lose exp.

There are four containers in this room: the center table, another table and bookcase to the left, and a chest to the right where you find:

Now head north and enter the first door (x 520 y 2000). Here you will find a couple of lesser Clay Golems. As the others they won't attack you. If you want killing them use blunt weapons. The others types of weapon doesn't work. You get 2000 exp for each Golem.

Continue your way and the corridor will lead to a door (x 1010 y 1745) and a battle with more goblins. Focus on the archers. Now open the door. Here you will find Rielev in a tube. If you agree freeing him and the others in the tubes you will receive a Crystal to revive the others and 4000 exp. On the table you find the Golem's Activation Stone. And the barrel (x 1275 y 1400) contains:

Now head back to the Sewage Golem and pretending you're its master give it the stone. He will run to open the doors. You might want revive the creatures in the tubes, but this is not necessary.
