Corrupted Infernal

Corrupted Infernals appear in the Nefarian encounter in Blackwing Lair. When Nefarian performs his warlock class call, any warlocks in the raid will immediately summon an infernal that will attack the raid.

The infernals scale to the warlock character's level, and can therefore present a danger even for high-level players soloing the instance. Subjugate Demon is useful for dealing with them.
