Inferno is an
warlock AoE spell that
summons an
infernal. This spell can only be cast outdoors and requires an
[Infernal Stone]. Once in the
infernal is summoned, it will automatically be under the effects of
Enslave Demon for approximately five minutes, after which it will break free and require another enslavement to be kept under control. Inferno has a
cooldown period of one hour. An Inferno has a pernament
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
[55] Kroshius' Infernal Core.
