Saving Wulbren is a side quest in Baldur's Gate 3, which begins when you visit the prison cells in the Moon Tower dungeon. If you're playing the role of the good guy, you'll encounter several prisoners and will definitely want to save them. In this guide, we'll tell you how to free the gnomes.
The quest becomes available as soon as you reach the Moon Towers. Right after entering, turn right and go through the only door. To the right of the column, there is a staircase to the dungeon — interact with it to get to the lower level.
Move along the right side and inspect the cell with the prisoners, then initiate a dialogue with Wulbren. The Tiefling will say he needs some lever or blunt object to get out. Mid-sentence, a guard will interrupt you. Response options:
Choose the option that suits your character best. If you fail the check, with the right skills, you can try again. But right now, we recommend avoiding a fight with the guard.
Return to the gnome and convince him that you want to help. As in any other quests, you can leave Wulbren and his companions to their fate:
We recommend choosing the Persuasion check option, as you only need to pass a difficulty class of 6. If your party includes a hero with high Persuasion and Charisma, you'll automatically succeed in the roll.
After that, listen to the prisoner. He will again ask you to hand him any weapon — even the simplest club or hammer will do (if your party includes Shadowheart, you can borrow her starting club). But you also have the option to steal Wulbren's weapon from the guard.
Note: Fighting the guards at this point will not affect how other guards in the tower perceive you.
In this case, you need to throw the club through the bars and wait for the gnome to break the wall. Everyone in the dungeon will automatically become enemies, and you will have to distract the guards.
There is also an alternative way to complete the quest — by breaking the wall yourself. For this, head to the western part of the location and find a breach in the wall. However, you cannot use a regular jump as the obstacle is too high. Use Enhanced Jump or the Gift of Flight spell.
Circumvent the cell and find the fragile wall. It's recommended to reach the wooden boat at the dock and break the chains first — this will further reduce the escape time.
In any case, the dungeon guards will be hostile, and you will have to kill them all to allow Wulbren and his companions to escape. It's also worth noting that the prison chief in the battle will use a magical shield, which complicates the task.
After that, return to the escapees. If the Last Light tavern is still operational, you can follow the gnomes there or stay in the towers.
