The following page of the Baldurs Gate 3 guide contains a walkthrough for a Save the Goblin Sazza quest. This solution will help you complete the quest.
- Free Sazza;
- escort Sazza out of Grove
- get to the Goblin camp.
This quest will activate while in the Druid Grove. At the back of this location, you will find two Tieflings standing by the cage in which Sazza is locked (M3;13). You can do the following during a conversation:
- don't interfere and let Sazza be killed.;
- stop the execution and save the goblin (if you pass the persuasion or intimidation skillcheck, you'll be able to complete it without a fight).
If you've decided to side with Sazza and you dealt with the Tieflings, you can talk to the goblin. She will tell you some about the priestess in the camp. After you release her, she will agree to lead you to the priestess.
You can open the cage with the thief's tools or by simply destroying the door. Once you get over this, you have to get Sazza out of the camp. To do this, the safest thing to do is to go up the rock shelf located right at the edge of the precipice. Jump over there, and after passing the perception skillcheck, you will find a door leading to the cave.
Inside, you'll encounter a group of goblins which you'll have to fight. Pay attention to the archer on the hill. Due to Sazza's low stamina, it is better to keep her away from the skirmish.
You'll also find unconscious Findal there. If you use a healing spell on him, you will be able to talk to him.
Note: you can also enter the cave from the other side (however, you must pass an aptitude skillcheck). Use it to get to the prison. That way, it'll be easier to fight. You will be able to sneak up on your opponents.
Finally, you must follow Sazza to the Goblin Camp.
