The combination of these two spells is precisely the origin of the dark legend of the "Hand of Winter":
In the legend, the Hand of Winter are Disability Wizards who have completely frozen their emotions, emotionless watchers.
They could instantly freeze their enemies' minds, making them lose the ability to resist, and could even freeze certain memories or deep-seated emotions in others, turning foes into friends...
Compared to the spells of the Ice Vein Wizards, the Hand of Winter was actually more skilled in the spells of the "Silence" Wizard. It was closer to the spells of the Soul Snatching School, albeit lacking some malleability.
The reason this new school was called "Disability" was not only because of the "loss of heat" from the frost, but also included the mental "loss of motivation."
Yes, Vladimir had never intended to use Elemental Power to attack Annan first.
