Frost Nova was a skill.
Yet Kel'Thuzad had found a new way to use it. As it was about to strike Rex, it did not become a torrent, nor did it unleash a full-on assault.
In its original form, Frost Nova was a single-target attack. Only someone struck by it would suffer its various effects.
If Frost Nova did not hit you, it would not cause you any trouble.
At Rex's level, dodging an ordinary Frost Nova would have been effortless. But the Frost Nova Kel'Thuzad cast this time was different. It was an area-of-effect skill, and he had made preparations for the moment it reached Rex. From Rex's perspective, those preparations were thorough indeed.
It had gone straight from a single-target attack to an area attack. That change alone made it almost impossible to guard against.
Once it became an area attack, Rex found it much harder to dodge.
To avoid the attack entirely, Rex would have to move outside its range. But Kel'Thuzad had launched it just as Anub'arak suddenly burrowed out of the ground beneath Rex. At that moment, Rex had already been thrown off balance.
Caught off guard, Rex had no good way to evade Kel'Thuzad's area skill. In the end, he could only take the hit.
Even possessing Ashbringer, an artifact in the strongest artifact sequence, did him no good.
Against a single-target attack, Rex could have defended himself with Ashbringer, cutting the attack apart outright. But dealing with an area attack like this was not Rexxar's strong suit. In the end, Rex had no choice but to let Frost Nova strike him.
The moment Frost Nova hit him, Rex felt his body stiffen.
His movements began to slow. The main purpose of this Frost Nova was to restrict what Rex could do.
