Glarghk Guhl Kashmas'nik was a waxy-skinned humanoid demon species. They used a retractable spike in each of their arms to inject a poison into their opponent. This caused the victim to experience extremely vivid hallucinations as long as it was in their system.

The only known cure was an antidote which was carried in its stinger. If the antidote was not taken, the hallucinations grew increasingly frequent, until eventually becoming their permanent state of mind. These demons could be summoned through playing a didgeridoo.[1]
