The Gray Imp is a tougher cousin of the common Imp. Gray Imps are thought to be either mutated or intentionally bred Imps, but regardless of their origins the Gray Imps have proven to be much more dangerous than their progenitors. They typically are found leading groups of their weaker relatives, though some Gray Imps are brave enough to venture out into the forests on their own in search of defenseless humans to rob. Like the Imp, Gray Imps are usually found in the forests of Coneria, the Temple of the Fiends, Pravoka and nearby areas.
