For Beholders, which you will start running into, back off, you can outrange them with your focused blast. Learning to kite is important, and once you have Cone packs of mobs don't matter, don't forget to cast any CCs you have though, to make life easier for yourself.
Work on getting Freedom of Movement, you can get it earlier from Ravenloft if you have that Death House, which is a very quick quest to run once you are used to it, there are more sources, the wiki is your friend.
So, if you started as Voodu's build it's not too hard to transition to this, and yes, this build still rocks.
