Instantly blasts the target for X Shadow damage. Only usable on enemies that have less than 20% health.
Restores 15% of your total mana after 5 sec. If the target dies within 5 sec, and yields experience or honor, the caster gains a Burning Ember instead.
Shadowburn is a warlock ability learned at level 47 for those with the Destruction specialization. Only usable on targets with less 20% health, it deals shadow damage, restoring mana to the warlock upon fading, or a Burning Ember if the target dies.
Requires a Burning Ember. However, if the target dies within five seconds, two Burning Embers will be created, resulting in an extra ember.
If you want to maximize your damage as a warlock in a party, then you should finish the mob using Shadowburn.
In duels, it is tempting to save the Shadowburn until you are sure that the opponent almost dies. A better strategy may be to use Shadowburn whenever possible, right from the start, as this will result in a higher damage output. However, this also leads to a higher Burning Ember consumption.
