Stinking Cloud
You create a 20-foot-radius Sphere of yellow, nauseating gas centered on a point within range. The cloud is Heavily Obscured. The cloud lingers in the air for the duration or until a strong wind (such as the one created by Gust of Wind) disperses it.
Each creature that starts its turn in the Sphere must succeed on a Constitution saving throw or have the Poisoned condition until the end of the current turn. While Poisoned in this way, the creature can't take an action or a Bonus Action.
Stinking Cloud 5e 2024 vs. 2014 edition differences
The 2024 version states the cloud lasts "up to 1 minute" and disperses only with a strong wind, whereas the 2014 version disperses after 4 rounds with moderate wind or 1 round with strong wind. The 2024 version applies the Poisoned condition until the end of the creature's turn, not retching and reeling, and imposes the Poisoned condition without requiring retching.
