Early on in Baldur’s Gate 3, players may find themselves facing down an iconic monster of Faerun—a hag. Hags are tricky fey creatures, and Auntie Ethel embodies with her illusions and lies. When all else fails, she’ll try to bait you into her hidden lair where tons of deadly traps lay in wait.
After fighting your way through charmed thralls, you’ll find yourself facing a field of Noxious Fumes. Besides being explosively deadly, they can chip at your health and leave you weakened for future fights. These noxious fumes are also found in various caves in the Underdark, so learning how to circumvent them will be vital to your travels.
How To Disable Noxious Fumes
Luckily, disabling these deadly traps is quite simple.
Once you get close enough to these fumes, your party will begin to make Perception checks. Successful checks will reveal rocky crevices, labeled as «Vents» which are the sources of each cloud of Noxious Fumes.
Once you’ve seen these vents, simply go into your inventory and look for a piece of junk that you no longer want—a scrapwood shield or goblin scimitar will work nicely. Throw this item onto the vent, and the cloud of Noxious Fumes should quickly dissipate.
Ensure that what you throw isn’t breakable, as the thrown damage might break it and render it useless, letting the fumes continue to escape.
Unfortunately, there are rare patches of Noxious Fumes that don’t have a clearly visible vent.
In these cases, you’ll need to stand far away from the cloud and ignite them with a fire spell or torch. The fumes will explode, clearing the path momentarily so that you can either see the Vent, or quickly pass through after dousing the flames.
Several of the Noxious Fume clouds in Auntie Ethel’s lair hide Peculiar Flowers that explode when stepped on, which can prove deadly in the flammable gas. Tread carefully!
