Quote: "Concentrated cyclone hits one target, suspending it in the air, dealing 2500% Ability Power as magical storm damage over 5 seconds. Each second, it damages a nearby target for 500% Ability Power."
First part of passive (2500% AP one target) doesn't work at all and the second one deals 2800% AP each second to one nearby enemy and to lifted enemy as well.
Fixed with the Trials Update as Sphere's system was replaced.
