Summons a meteor from the Twisting Nether, causing 200 Fire damage and stunning all enemy targets in the area for 2 sec. An Infernal rises from the crater, under the command of the caster for 1 min.
The master of every infernal worries not about its death, but that it might survive too long.[1]
Inferno is an warlockAoEspell that summons an infernal and requires an [Infernal Stone]. Once in the infernal is summoned, it will automatically be under the effects of Enslave Demon for one minute, after which it will die. Inferno has a cooldown period of ten minutes. An Inferno has a permanent [Immolation] aura that breaks CC. In Alterac Valley players tend to over estimate an Infernal's strength and can be used as a rather effective distraction target.
This spell can be learned from [Grimoire of Inferno] or the quest Template:Questclass. However it is much easier for high level warlocks to get this spell through the book rather than the quests. The book has a roughly 3% drop rate from Scarshield Warlocks in Lower Blackrock Spire, and should drop after 1 or 2 runs.
