1. Understanding the Noxious Fumes Trap
The Noxious Fumes in Bg3 are scattered throughout the entire Bg3 map, most of which are in Auntie Ethel’s Overgrown Tunnel, a trap-filled and dangerous area. Hidden vents on the floor constantly expel the fumes, causing poison damage for those who don’t get out quickly enough. The flowers growing within the fumes are also peculiar, with a reaction to fire of some kind; the fumes combust when they come into contact with flame-based attacks or spells. Without planning, these fumes can really trap you and damage your party, leaving you very unable to move and limited resources.
2. Preparation for Moving into the Noxious Fumes
For the first part, ungroup your party, except for the character with the highest Perception, and have them scout the area. If Bg3 companions accidentally wander into the poisonous zone, then this step becomes essential for preventing accidental combustion. There are Perception checks that point out the hidden vents under the fumes. For ultimate safety, save the game before every check in case of failure. With this strategy, if you miss a vent, you can still detect it without having to restart the sequence entirely.
3. Locating and Targeting the Peculiar Flowers
After identifying the vent and flowers, open up by casting a fire spell or a ranged attack into the vent and flowers. The explosion made by the fire breaks apart the fumes and enables you to see where the vent is. When the fire spreads, you must ensure that no characters are in any proximity to the fumes, as the explosion will hurt everyone nearby. Don’t move forward until the flames have died down. That way, you'll only have to ignite the flowers once and momentarily clear the path.
4. Closing the Vents to Suppress the Fumes
Once you spot the vent, open your inventory and left-click on an item you can place on top of it that will seal it from letting the gas seep out. Some ideal items would be crates, barrels, or even a skull. Avoid using fragile objects; they may break on impact, leaving the vent exposed and requiring you to start again. If the vent is blocked, the fumes should dissipate, allowing your party to pass through the area safely.
5. Moving through Clouded Conditions at a Constant Pace
The Overgrown Tunnel in BG3 is typically lined with many vents. You will need to do the above process in every section. Pay attention to your environment and seal every vent as you move forward. When you clear each vent, you should check Perception cues for more traps and vents further down the tunnel. This way, you'll make it to Auntie Ethel's lair without wasting many resources or getting your party in deep trouble.
6. Consumables and Potions
Provide antitoxin potions or resistance potions to your characters when they have to pass through a section where fumes linger. These consumables can be very useful in case the party can't or won't block off a vent. Consider spells that enhance constitution or poison resistance to help your party further if they're staying in the Bg3 Noxious fumes.
7. Managing Health and Spell Resources
Manage your Bg3 party's resources as you step through these traps. Keep your Healer or Cleric handy and ready to nullify poison damage from restorative spells if someone takes damage from the fumes. Make sure you have enough healing spells or items in your inventory in case someone accidentally steps into a gas cloud.
FAQs
Rushing is not recommended because the fumes apply damage constantly and may even incapacitate weaker party members.
Once you seal a vent, it stays sealed; even when you backtrack, the fumes cannot find their way back through the vents.
Though it really doesn't matter if it's any fire spell, area-effect spells such as Fireball certainly do make sure that you touch all the flowers in a go.
Passing the Perception check is very critical as you can sense vents and avoid getting trapped.
Conclusion
Baldur's Gate 3's Noxious Fumes are no joke; getting through them requires patience, strategy, and a bit of preparation. Using perception skills, staying far away from Auntie Ethel, and picking your fire attacks carefully can help you safely navigate Auntie Ethel’s perilous lair. Furthermore, keeping some reserve of health resources and resistance potions will mean that your party will arrive at the Hag’s lair fully prepared. With this systematic approach, it will be possible to take the fume-filled obstacles in your path one by one, increasing your chances of success as you face down Auntie Ethel.
