Blizzard announced at Gamescom this year that Kel’Thuzad would soon be floating his way from Naxxramas to the Nexus as the Heroes of the Storm’s 65th hero.
In proper Gamescom fair, they revealed the hero by means of a pretty nifty animated trailer which not only showed off Kel’Thuzad, but some new skins for Sonya, Jaina, and Zagara.
Kel’Thuzad’s skillset includes Death and Decay, which hurls an exploding orb at the enemy. Frost nova is a nova… of frost, and an interesting one: Chains of Ice. Apply it to two enemies and pull them both together. His ults include Frost Blast and Shadow Fissure. The former deals damage in an area and stuns for 1.5 seconds. The latter primes an area to explode after 1.5
