Ice speed reduction

[- D E A T H S T R O K E - 1,772]

there are many types of classes with ice effects skills on Game, but every class has its own reduction effect, for E.G. inertia it says -34% speed reduction and distortion -22%.

i would like to know the % of speed reduction of :

*Glacial spike (priest)

*Ground pike (pike)

*ice meteorite ( priest)

*Frost wind ( assassin)

* Frost javelin (atalanta)

for eg. it seems like ice meteorite speed reduction is like 10%, and ground pike seems to be -50%, even though both skill have the same ''ice effect''

so i would like to know the speed reduction in % of those skills.
