A free mod for Witcher 3, by flamingdiaper4U.
There are various types of poison clouds in the world of video games. They may appear on the ground or in the air. In many cases, they may be simply ignored. However, when they are too large or occur in an area where there is not enough oxygen, they can cause players to become sick and, in some cases, even die. Better Toxic Clouds is a mod that removes the poison clouds from underground areas in the game. It can be installed through NMM or by extracting the downloaded zip file to the Mods folder.
