A powerful Ice Gear that allows the Ice Elemenstor striking it to turn his entire body into living ice.
There's snow, there's Ice, then there's Living Ice. An Elemenstor skilled in this power can actually take surrounded liquid and add it to his own mass at will. Being able to grow his limbs, jutt out claws from his arms, or even just being able to add the water to his senses, he can find where you are hiding, and strike you from anywhere.
