So far the spell that stands out in my mind is Jolt because it is unbalanced, some might argue it is broken. I have to wonder if they put a rough draft version in, instead of the final version.
There are lots of attack spells. There are spells converted from previous Necromancer Games books. There are spells that exist only to fill "gaps" in the fire/cold/acid/electric circle. There are spells converted from previous editions of DnD.
There are also some feats and 1 template for a spell.
