Hurricane is a lv 30 Druid skill from the elemental tree.
It gives synergy to Arctic Blast, Cyclone Armor, Twister and Tornado, but only receives synergy from Cyclone Armor, Twister and Tornado.

It basically creates a force of wind that surrounds your character while you stay in the calm eye. The damage it does is cold damage meaning it can be very easily resisted in PvP, comparing to Tornado.

I actually remember these stuff.
