Blasts the target enemy unit with damaging frost, dealing area damage and slowing movement and attack rates for 4 seconds. The primary target receives both base and area damage.

Applies a magical frost shield around the target, reducing damage from attacks against it. While the shield is active, ice magic will affect nearby enemy units every 1 seconds, dealing minor damage and slowing them.

CHANNELED - Hypnotizes an enemy unit, causing it to move towards a point between the two of you and drains a percentage of its current mana.

Creates an Ice Spire at the target spot, slowing enemies around it. Can take 4 hero hits or 8 creep hits and when destroyed it will create a Frost Blast around it.

Chain Frost can be cast on the Spire and can bounce to the Spire and damage the spire by 1 hero attack if there are no other enemies in range.

Lich can cast Frost Shield on the Spire. Each Frost Shield tick will heal the spire by 1 hero attack.

Releases an orb of frost that bounces between nearby enemy units up to 10 / 10 / 10 times, slowing and damaging each time it hits. Each bounce increases the damage for the subsequent bounces. Chain Frost lingers on its last target if it fails to bounce and can bounce again if new targets become available.
