Frozen Tempest

Icy Enchantments teleport to a random enemy and channel a Frozen Tempest, increasing their vulnerability to attacks by 100%.
The tempest creates a dome of frost, inflicting 4.19817 Frost damage to units inside and pushing them towards the outer edge of the dome. Players who cross this threshold will be stunned in place, creating a block of ice that must be destroyed before the stun is removed.
