need to gear a bit towards it though, meaning ias not too high, good mit and ehp in general, apoc and ls.
U have to account for the ap regeneration, so either 20 apoc + astral or power hungry (pur on gear?) or u could go with 20 apoc and tals 4 set or use less apoc + more some ap reg skill like arcanot, ap reduction skills like power of the storm os ds prism. ur choice.
basics is just sleetstorm + teleport + magic weapon of choice(depending on how much ls ) + armour of choice (depending on ur mit basically). the other 2 spells are a bit open depending on ur needs gears. if u use cm fn, ds eb are options or u can buff urself harder with sparkflint and use one cd based spell only. the passives cold bloded obviously + cm + ap regen of choice.
the build is really open for variations.
