Inferno is essentially the Sorceress' magic blow torch. Consuming a variable amount of mana per second casting time, this skill shoots a jet of flame from the Sorceress' fingertips beyond her and in to her enemies. It synergizes with Warmth quite powerfully so, allowing its damage potential to skyrocket over time. The length increases with additional skill points invested so Sorceresses can wreak havoc from long distance.IF AT ALL a player maximizes Fire Mastery, Warmth and Inferno, this turns out to be the most powerful attack the sorceress has. Also using it as a secondary button skill, targeting an empty area and holding the button down allows to use a powerful jet of flame which can be quickly directed to incoming enemies.
Balrog demons and Fetish Shamans also have a version of this spell.
Using this spell, a Sorceress can reach into the depths of her being and send forth a gout of fire, incinerating all opponents within its reach.
