Gascraft is an addon mod for Engineer's Toolbox, which adds a variety of gases to caves. These gases flow similarly to water, but travel upwards instead of downwards. Like water, they can cause suffocation damage. As of Minecraft version 1.7.10, the mod was merged into Engineer's Toolbox itself and no longer exists separately.
