Hello :
1- Freezing Puls on staff, Vaal Storm Call on chest
2 Chest is very bad, change to min. 250/300 ES
3- Ring bad, need other , Amulet this same
4 what the hell you have on Helmet ? This is nothing from build, somethings yours combinations, I thing
My advise, one more time look at video and try see the way, there are very good explain.
I play with this built, but use Tharyns Shiver, for me its better
Good luck and Have Fun :)
