Gas Pillar

Gas Pillars are rocky, hole-ridden outcrops found throughout the world that emit Poison Gas around themselves. Gas Pillars are found in groups.

Behavior

Gas Pillars emit a steady cloud of Poison Gas. In some areas, the gas may extend outward further than where the Gas Pillars are located.

Gas Pillars are typically found around various collectibles and exploration rewards that can be found around the map: Somersloops, Mercer Spheres, Power Slugs, and Crash Sites.

Gas Pillars are immune to most forms of weaponry but can be destroyed by the explosions from Nobelisks, Cluster Nobelisks, Nuke Nobelisks, and Explosive Rebars. Once destroyed, Gas Pillars do not respawn.

A Gas Mask combined with Gas filter is necessary to navigate in Poison Gas to prevent taking damage.

Small structures, such as Power Poles or Conveyor Poles, can be built on top of Gas Pillars.
A Hover Pack generally allows Pioneer to fly over the Gas Pillars with ease, sometimes even collecting loot from a safe distance thanks to the interactive range extension when flying with a Hover Pack.
Vehicles can be used to explore past areas that are cut off by gas, as the player takes no damage from anything whilst in a vehicle.
