His Dark Horizon Intelligence skill gem · Spell, Buff, AoE, Cold, Storm

IntelligenceSpellBuffAoECold
DNT-UNUSED Create a storm of deathly energies that Empowers your Mana-costing Spells with Cold damage while you remain inside it. Maintaining the storm constantly drains your Mana, and spending more causes it to drain faster. As the storm persists it creates slowly expanding Chilled Ground. Enemies that enter the eye of the storm are Blinded. When you leave the storm, or run out of Mana, the storm ends and unleashes a death-wave, damaging enemies on the Chilled Ground.
