Deals Shadowflame damage to an enemy target, increasing the duration of Immolate or Unstable Affliction by 6 sec.
Fel Flame is a new warlock ability that comes with Cataclysm, learned at level 81 for 23 40 . It was first announced in the Cataclysm warlock preview.
Fel Flame is a quick-hitting spell that deals Shadowfire damage. This is similar to the mage ability [Frostfire Bolt], in that the lower of the two resistances (in this case shadow and fire) on the warlock's target will be used for calculating its damage. Additionally, Fel Flame refreshes the duration of [Immolate] and [Unstable Affliction]. The goal for Fel Flame is to provide a spell that's good for mobility and for use by Destruction and Demonology specs. The ability uses green fire. Instant cast.
