Whirlwinds Blind and Slow the movement speed of enemies within them. If their creator crosses the edge of the Whirlwind it collapses, damaging and Knocking Back enemies caught inside. The collapse deals Melee damage.

Trying to create a Whirlwind that would overlap with an existing Whirlwind instead moves the existing Whirlwind and grants it a stage, making it larger and more damaging.

A Whirlwind that overlaps an allied Elemental Ground Surface takes on that element, gaining 50% of damage as the corresponding type and applying the Ground Surface's debuff to enemies inside the Whirlwind for 8 seconds.
