Evil Spellcasters = Evil Spells
1. Get Monte's Book of Eldrich Might I and II. Lots of evil spells in there. Also, see if you can find the old Necromancer's Handbook.
2. Barbs of Shadow - Chains forged of darkness with fishhooks at their ends spring from the shadows in all directions and rip the flesh off your target.
3. Blood to Glass - the name says it all
4. Fleshcrafting and Bonecrafting - Can bend, warp, rend, and sculp flesh and bone as if it were clay. (Ever play Vampire?
)
5. Living Shield - Grab somone's spin and use it as a handle. Their body becomes an animate shield. (Another Vicissitude reference.)
6. Soul Burn - Does both fire and negative energy damage. (Magic: The Gathering reference)
7. Living Puppet - Veins rip from opponents arms and act like marrionet strings which you control telekineticly.
8. Bone Soldier? - The flesh peels of your opponent to reveal a skeletal warrior under your control.
9. Blood to Acid - again, the name says it all.
10. Haunting Memories - Character mentally experiences the death of everyone that ever died within the spells range. (Nasty in graveyards!)
11. Betrayal of the Body - Character's own bodyparts turn against him. (Ever see Evil Dead?)
12. Wall of Maggots - see Blood to Glass
etc....
Also, don't forget to take the Spell Sculpting Metamagic feat.
