I have a Wiz build of Wiz 3 - Ele 3 - Rune - Enchanter (Ice & Lightning skill specialty)
So basically the only thing great about Freezing Sphere is it does greater damage than Wiz’s Energy bolt. (So I didn’t get the Energy Bolt skill)
But as the name implies at least IMC can improve the skill and be a bit useful. XD
Hail can freeze but Freezing Sphere can’t.
