The other cunning overlord of the Burning Legion, under Sargeras’s command. He is well-versed in the arcane arts, far exceeding Archimonde’s capabilities even before being enlisted into the legion’s service. He prefers to defeat his enemies with manipulation and cunning, often not intervening unless the situation demands it. Unlike Archimonde, he is more, tolerant of his servants, unless he deems them to be of no further use.
He has all the abilities of Archimonde
He is a master of illusions, and enslaved the dreadlords(a testament to his power), and is even more powerful than Archimonde
He prefers to use forms which will strike awe into the hearts of beings.
Kil’jaeden, upon joining Akoni, brought far more demons into his fold, bringing in large numbers of demons and races. Kil’jaeden is one of the strongest demons under Akoni, whom Akoni consults when manipulating people or making deals.
Kil’jaeden’s magic has also improved by leaps and bounds, and the Fel Stalkers within the legion are now literally immune to all magic. He can easily wipe the enemy’s mind with a flick of his finger, obliterate them, or turning them into his pawns. He often uses manipulation instead, since powerful magical beings would likely resist him.
