CHANNELED - A powerful slowing and damaging current that grows stronger as it's channeled. Lasts up to 10 seconds. Enemies are slowed for 1 second after leaving the area or the spell ends.

Whenever an enemy unit dies while afflicted by one or more of Warlock's abilities, a minor imp is summoned that lasts for 15 seconds and explodes on death. Imps will automatically seek out nearby units, favoring fatally bonded heroes, and will explode when reaching their prey.

Summons a Golem from the depths, stunning enemies for 0.8 seconds. The Golem lives 60 seconds, takes reduced damage from spells, has increased Slow Resistance, has Permanent Immolation and Flaming Fists on attack.
