To break the Oath of Vengeance in Baldur's Gate 3, you need to perform actions that go against its core tenets of pursuing justice and showing no mercy to the wicked. The most reliable and commonly reported method is to free Sazza, a female goblin imprisoned in a cage in the Druid Grove, using your Paladin character (not a companion). Specifically:
- Protect Sazza when she is threatened.
- Win persuasion checks to prevent harm to her.
- Wait for the Tieflings guarding Lae'zel to leave or kill them.
- Use your Paladin to pick the lock and free Sazza from her cage.
Doing this breaks the Oath of Vengeance and triggers the Oathbreaker status
. Other ways to break the oath include:
- Attacking the Tieflings imprisoning Lae'zel early in Act 1.
- Letting the hag Auntie Ethel live after encountering her.
- Allowing Astarion to become a vampire ascendant in Act 3.
- Various actions that involve showing mercy or making deals with evil characters, which violates the oath's strict stance against mercy and bargaining with wickedness
Note that some actions only break the oath if done by the Paladin character themselves, not by companions
. In summary, the surest early way to break the Oath of Vengeance is to free Sazza yourself in the Grove, or to attack the Tieflings holding Lae'zel. Other story choices later in the game can also cause oathbreaking
