Slow duration reduced to 1.5 from 2.
Updated the tooltip to reflect slow information for single target and damage-over-time slows.

V1.0.0.63

Slow duration increased to 2 seconds from 1.5 seconds.
It will now trigger on dealing non-periodic spell damage, instead of spell hit. This means that spells like Destiny or Time Warp, which previously triggered the effect, won't anymore; however, Rupture will now slow on dealing damage instead of on the initial cast, Powerball will now trigger the effect when you hit units, etc.
