Infernal death was a slow-acting poison that caused death within 12–48 hours. This poison was highly reactive and was administered through spicy dishes where it could be ingested. Victims who resisted the poison's deadly properties still developed a debilitating rash that lasted for several days.
The only means of curing someone affected by this poison was by casting neutralize poison and protection from fire with a ten-foot radius simultaneously. Thus, two clerics were needed to cure the victim.
