Vortex is a cold spell that explodes dealing damage in area around the player and leaves a ground effect that chills (similar to chilling ground) and deals cold damage over time.

Skill functions and interactions

• The Vortex consists of two parts: explosion and a ground effect.
• Stacking: If an enemy is standing over multiple vortex ground effects,only the one with the highest damage per second will cause damage at any given moment. This is consistent with other damage over time ground effects, such as caustic cloud and burning ground.

• Modifiers to Spell Damage apply to this skill's Damage Over Time Effect: Modifiers to spell damage only apply to the ground effect portion of the skill and do not affect other sources of damage over time which may be applied by the explosion, such as poison, the Decay Support, or ignite from The Three Dragons.
