Cyclone CoC Raider - Elemental spells

Hi all,

I am trying to theorycraft a Cyclone CoC Raider which casts elemental spells. I am thinking of using lightning spells at this point, as I have tried out Shock Nova, Arc and Ball Lightning in a Cyclone CoC setup and it seemed quite fun. However, I am happy to keep my options open in respect to fire and cold spells.

One of my main goals is to achieve a very high rate of mobility through movement speed, which will also increase the speed of Cyclone.

In regards to the passive skill tree, I am thinking along the lines of this:



I don't necessarily have to go with an ES build.

Any ideas?
