In Baldur’s Gate 3, noxious fumes and poison clouds look similar, but you have to deal with the two toxic gases in different ways. These obstacles will bar your passage several times during your journey, and knowing how to deal with them is crucial since they can quickly kill you. Fortunately, you can deal with these pretty quickly as they always work the same way.
How to clear noxious fumes in Baldur’s Gate 3
Clearing noxious fumes in Baldur’s Gate 3 is easy, but it’s also very dangerous. If you accidentally inhale them, you’ll take 1d4 Poison damage each turn. You must also roll a Constitution check. You’ll take an additional 2d4 Poison damage if you fail or half that if you succeed. Early on in the game, when your HP is low, that can be fatal quickly.
Noxious fumes are also very flammable, and using that property is the best way to clear them. Sending a Fire Bolt or tossing a lit torch into the fumes will detonate them. In many cases, that’s the end of it, and you just have to wait for the flames to dissipate, and you can pass freely.
However, sometimes noxious fumes will be emitted by a vent. In this case, they’ll reappear after a short time. If you want them to remain gone, you must disarm or destroy the vent.
How to clear poison clouds in BG3
Making things confusing is the fact there are also Poison Clouds in BG3. These aren’t flammable, but they’re also not as damaging. If a character is affected by one, they’ll take 1d4 poison damage per turn and suffer a disadvantage on attack rolls and ability checks. So, not quite as bad as noxious fumes.
However, poison clouds aren’t flammable, which makes clearing them harder. Most of them are emitted by vents which can be turned off or blocked with objects. Many times these require a perception check, and if your party doesn’t spot it, then you’re stuck dealing with the poison gas. Fortunately, if this occurs, the Gust of Wind spell can also temporarily dissipate the gas.
