Surround yourself in a vortex that continuously deals 15% weapon damage to all enemies within 10 yards. The vortex lasts 6 seconds and is refreshed each time you strike an enemy with a melee attack. Landing a Critical Hit has a chance to increase the vortex effect up to 2 times for a total of 44% weapon damage to nearby enemies.
So what counts as a melee attack?
Best Answer
I tested every skill and the following attacks refresh Sweeping Wind. It should be noted that Sweeping Wind is refreshed when the skill is used instead of when the attack hits.
Normal Attacks
All Primary Skills
All Secondary Skills
Dashing Strike
Seven-Sided Strike
Finally, using Sweeping Wind again will refresh the timer and maintain any stacks.
Although Sweeping Wind's description specifies striking an enemy, it can both refresh and stack (via a crit) when one of the above attacks is used against a destructible piece of the environment. It can, however be difficult to reach the item you want to strike before Sweeping Wind itself destroys it. Thus, this effect can most easily be seen by using Dashing Strike to charge and hit an item.
