I play a warrior and I can say that nothing is a more easy kill than killing a frozen character <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />.
I got this sword (I am less than 20th level) which has Freeze 2 and 5 charms... Singing Blade or something like that... Well, I am butchering everything arround <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />.
