Mage/Dark Wizard Any Good Builds For Cascade?

i used to try doing a medium or id guess semi decent Judas build but the "almost dying" part wasnt too good so wanted something that also reached multiple types of damages. but i dont know what powder to use on it or what items to make a decent enough for places to farm mythics in the future like the frozen warriors or some other places. any good ideas?
