Anyone who plays the Dark Urge in Baldur’s Gate 3 will be forced to make more than a few gruesome decisions during their playthrough. One of these choices is killing Isobel, a Cleric of Selune who resides in the Last Light Inn. However, this choice should not be made lightly, as killing Isobel will irrecoverably impact your relationship with your companions and prevent you from completing certain quests. This begs the question: is the reward you get for killing Isobel enough to outweigh its price? Here are the rewards and consequences for killing Isobel in Baldur’s Gate 3.
Should You Kill or Spare Isobel in Baldur’s Gate 3?
“When you reach the Last Light Inn in Baldur’s Gate 3, you will meet Isobel, who provides the Inn with magical protection from the Shadow Curse ravaging the surrounding area. Soon after this introduction, Flaming Fist Marcus will assault the Inn with a pack of winged horrors. If Isobel survives the battle, you will be visited by Sceleritas Fel, your demented Goblin “butler.” who will task you with assassinating Isobel in exchange for a special reward.
If Isobel is killed during the fight and you don’t kill her immediately, Sceleritas Fel will still visit your camp, but he will ask you to kill your romance partner to prove your devotion to your “cause.” If you don’t tell your partner about Fel’s demand, you will lose control of your Urge in your sleep and kill them. To rub salt in the wound, the rest of your companions will turn on you and try to kill you once they find out what you’ve done, so you’ll be forced into an all-out fight with the people you care most about.
If Isobel survived the battle with Flaming Fist Marcus, head back to the Last Light Inn. You will be given two options when you approach Isobel: kill Isobel or talk to her to receive a Dark Urge moment. If you choose to kill her, you will kill her immediately. However, if you speak with her, you will battle her instead. Either option doesn’t matter as long as she ends up dead.
After killing Isobel, head back to your camp and rest again. Fel will revisit you, and you will be rewarded with the Slayer Form. Functioning as a dark variant of the Druid’s Wild Shape Ability, Slayer Form allows you to assume the form of a demonic beast that can tear your enemies to shreds. Fel also asks you to finish what you started by annihilating Isobel’s bloodline, the Moonmade family.
However, you should know that killing Isobel will allow the Shadow Curse to penetrate the Inn, killing everyone inside. Many NPCs seeking shelter in the Inn are essential to completing certain questlines, preventing you from receiving the rewards at the end of them.
The following actions can’t be completed if you do kill Isobel:
- Dammon will be killed by the Shadow Curse, meaning he won’t be able to repair Karlach’s Inferno Engine and continue her questline.
- Art Cullagh will killed by the Shadow Plague, which prevents you from learning a vital clue about the origins of the Shadow Curse and completing the quest that allows you to recruit Halsin fully.
- Jahiera, the Half-Elven Druid, will be disgusted by your actions and refuse any attempt to convince her to join the mission to infiltrate Moonrise Towers. This prevents you from starting the quests you have to complete to recruit her to the party.
If you don’t want to accept these less-than-desirable outcomes, you can escape this situation without killing anyone. If you don’t kill Isobel and are honest with your partner about your Urge, they will knock you out and tie you to a post, allowing you to make Wisdom saving throws to resist the Urge. This Saving throw has a high success threshold, but your partner will give you a slight boost, so hope the dice are on your side or be ready to reset to your latest save if you are deadset on fighting the monster inside you.
