Fel Domination

Fel Domination is a warlock talent and ability which reduces the casting time and mana cost of the next minion summon spell within a 15-second window.

Talent improvement
This talent is particularly useful when combined with Master Summoner which reduces all of your summons' cast time by 2/4 seconds and 20%/40% mana cost. This gives a maximum benefit of a 0.5-second cast.

Tips and tactics
One of the best uses of this is when your Voidwalker is near death; use its Sacrifice ability to give yourself up to 30 seconds of protection. Then cast Fel Domination and summon a Succubus, Felhunter or Imp (so long as you have at least 1 point in Improved Firebolt) to help finish off the (hopefully weakened) enemy.

Enemies of the warlocks would have lay people think that the demons a warlock summon are invincible and cannot be defeated. This is, in reality, nothing more than anti-warlock propaganda. As all warlocks know, summoned demons (other than the Infernal and Doomguard...well...maybe not the Doomguard) are more cuddly and fluffy than threatening and a Warlock can often find him/herself in the open without a demon to protect himself.

Some warlocks call this the 'Oh Crap' maneuver...
