BG3 Balthazar is one of the most important bosses you will come across during this quest and he possesses the power to raise undead soldiers.
Deciding to fight Balthazar is important for the decision to save Nightsong or kill her in the game. That decision can impact your romance with Shadowheart should you pursue it.Balthazar Location in BG3
You will find Balthazar far into Thorm Mausoleum. To meet Balthazar, you must head over to the main entrance to the Mausoleum where you will encounter Raphael, asking you to kill Yurgir. The entrance of Thorm Mausoleum is located at the coordinates of X: -189 Y: 110. After reaching the location, head inside the Mausoleum and make your way into the room straight ahead. Find the Gauntlet of Shar
There is a door in the room that you must open. It leads you to the next area with a Traversal Gem at the center. The room is filled with traps that deal a ton of damage to your health. However, if you have Minthara as your companion or Astarion, you can easily detect them.
These traps are scattered across the room. Therefore, the best option is to walk beside the walls and avoid stepping onto any traps in the middle. Walk your way to the door at the front and open it. This will open the side walls revealing the nest area.
To reach Balthazar in BG3, head inside the next area and step on the platform ahead with the Traversal Gem on it. This platform leads you down to the Gauntlet of Shar in BG3. Enter the dungeon and go forward while unlocking the Stone door ahead.
The door leads you to the Umbral Gem. Take care to avoid the shockwave it spews out since it will damage you. It is best that you lean into the wall and move along the path to the left to find a Bulky Door. Use Thieves’ Tools to lockpick the door and head inside. Fight the Phantasms
There is a Sarcophagus atop the platform ahead. Loot it to receive a bunch of items before heading over to the waterfall area to the left. Jump onto the stones that lead you to the area with large mushrooms. However, be warned as this area is filled with Phantasms. Reaching Balthazar is not an easy task in BG3. Defeat the enemies and move to the eastern part of the area down the stairs and enter the Double Oak doors at the end. Find the Reconstituted Duelist
There is another Double Oak Door inside the building. You can use the lever next to it to head inside. As you enter the next room, you will find the Reconstituted Duelist on the platform ahead. Talk to him and choose the dialogue option given below:
Z’rell sent me, looking for someone called Balthazar.
This triggers a small fight between the enemies.
