[[Imperial ]] and [[Chaos]] [[flamer]]s fire a mix of liquid chemicals which ignite on contact with the air. The flaming chemicals stick to the target, burning it up. The fact that the chemical sticks to its target and continues burning on its own accord, means that those who are not killed instantly die horribly as they are burned up. The most common substance used is known as [[Promethium]], which is sticky and similar to modern day napalm. The flamer fires a burst of expanding flames, making the weapon effective at killing enemies in cover.
