The Novamancer is a Necromancer build which should be able to wipe out a fairly large group of enemies with a combination of Lower Resist and Poison Nova. The Novamancer focuses on a balanced build with high poison damage with the Poison and Bone Spells skill tree. This build gives the ability to inflict high damage with the poison skills AND also allows you to have some "distractions" so to speak so that you won't be the one taking all the damage. While your Golem is standing between you and your enemies, you're free to unleash some high poison damage.
