This achievement is tricky on the second step. If you don’t confirm Sazza is alive before moving to Act 2, you may be locked out of She Cannot Be Caged. Like most questlines in BG3, there are multiple ways to accomplish these. You will encounter Sazza 3 times during your playthrough if you manage to free her to make it to the next location.

First, Sazza will be a prisoner in the Emerald Grove during Act 1. Free her by talking with her captors. Then, talk with Sazza and convince her that you are there to help by escorting her safely out of the grove.
Goblin Camp
The second encounter with Sazza is at the Goblin Camp. Meet her outside the camp, and she will begin escorting you inside. You don’t need to follow her to her destination.
Create a manual save before interacting with Sazza in the Shattered Sanctum. If something goes wrong, you will need to backtrack to here.
Once you find her in the Shattered Sanctum, she will introduce you to Nightwarden Minthara. Side with Sazza and say “She’s telling the truth. She didn’t know.” Then agree with Minthara by saying “I’ll get it done.” After that point, wait for Minthara to leave the camp. She won’t actually leave the sanctum until you walk near the entrance and the troops march off. Then, you’re free to take out the goblin leaders. Just watch for Sazza standing in the main hall and don’t kill her.
Don’t kill the goblin leaders before saving Sazza from Nightwarden Minthara. If you do, she will fight with the goblins and die. Killing the goblins before Minthara leaves the camp will also result in her death. After Minthara marches off, leave the camp, return, and cleared out the Shattered Sanctum. Then, fast travel out of the camp and across the map (like Emerald Grove). Upon returning to the sanctum, Sazza can be found standing in the main hall by herself. She should show as yellow/green, but you cannot talk to her. If she’s in this state or you left the goblins alive, you may continue to Act 2.
Moonrise Towers
The third encounter with Sazza should be when you arrive at Moonrise Towers in Act 2. Enter the Throne Room on the main floor and a cutscene will begin. If you see 4 goblins, including Sazza, you can earn the achievement/trophy. However, if you only see 3 goblins, something went wrong in Act 1 and you will need to reload your save.
Choose the following dialog options to ensure she is safely released and the achievement or trophy will unlock.
- Don’t kill them! They’re loyal followers of the Absolute.
- They’re faithful to the Absolute, I’ll give them that.
- What am I meant to do with them, exactly?
- Guards. Release them.
Immediately after you order their release, the She Cannot Be Caged achievement will unlock.
