Baldur's Gate Wiki

Gas Cloud is an innate ability effect available to most Iron Golem creatures in the game saga. In some ways, it is similar in function as the 5th-level Wizard Spell Cloudkill, but it is applied on top the golem, has a smaller area of effect, and only has a chance to apply a Poison effect to opponents.


The spell effect is interruptible but takes little time to deploy. The scripted targeting will fire over the golem or it can be aimed at a detected target. All creatures within the area of effect and the cloud animation that are not immune to the Poison effect must make a saving throw vs. Death/poison with a -2 penalty or be subject to a "poisoned" status effect. The affected creature will have a poisoned icon displayed and suffer 1 Poison damage per second for 18 seconds. The effect is non-magical, and thus bypasses magic resistance, can't be dispelled, and ignores spell level protections such as Minor Globe of Invulnerability or Spell Deflection.

The duration of the innate poison cloud is 3 rounds.

In an unmodded game the golem will apply the cloud after two rounds of melee combat, and then again five rounds later and continue that interval.

The spell Zone of Sweet Air is not coded to remove the cloud effects from this spell's projectile. Projectile 224 isn't listed in the clearair.2da file, and thus the playr has no way to disperse this cloud.

The Sword Coast Stratagems mod's AI revisions for the Iron Golem are more aggressive with the use of this cloud ability. It launches it at greater distances from a detected enemy and reapplies the cloud every three rounds.
