when i leveled my necro i used a dts build and i used to play with dtsx7 and 1 melee pet for frenzy or fear...
fear is no longer so good, 'cos it's not instant anymore, but frenzy can be still handy...
i think you can try something like this...
"in the depths of a mind insane fantasy and reality are the same"
