Stopping the Boon of Bhaal in Baldur's Gate 3 requires specific actions during a critical narrative moment. Once fully manifested, it's irreversible through normal gameplay.
Prerequisite: Refusing Bhaal's Gift
- Encounter Orin the Red: You must face Orin in the Temple of Bhaal within the Undercity Ruins.
- Reject Bhaal's Influence: During the dialogue after defeating Orin, explicitly reject Father Bhaal's offer of power and refuse to become his Unholy Assassin/Slayer.
Stopping the Transformation (If Already Accepted)
- Approach the Altar: After refusing Bhaal, interact with the ritual altar behind Orin. Withers will appear.
- Seek Withers' Aid: Choose the dialogue option asking Withers for help regarding Bhaal's influence or the voice in your head.
- Undo Bhaal's Legacy: Withers will offer to sever the connection to Bhaal. Accept this option. This stops the active transformation process and removes the Boon of Bhaal debuff (prevents passive bleeding).
Critical Consequences & Limitations
- Irreversible Choice: If you accepted Bhaal's power and transformed into his Slayer form without interacting with the altar/Withers immediately after refusing, the Boon becomes permanent.
- Locked Out of Non-Bhaal Endings: Accepting Bhaal's legacy locks you into the Dark Urge's Bhaal-aligned story endings.
- Sacrifice Required: Successfully stopping the Boon permanently sacrifices the acquired Slayer Form power.
- Act 3 Completion: This specific sequence at the altar is the only way to stop the Boon; it cannot be undone later.
Key Takeaway
Immediate action at the altar with Withers after rejecting Bhaal is the sole method to stop the Boon of Bhaal. Failure to do this at that precise moment renders the condition permanent.
