Rayof sickness and color spray.
Color spray grants blindness to creatures that fail the save in its area, but onlyfor 1 round. One might argue that it is mediocre, but there are better ones in the spell lists.
Ray of sickness is just horrid, it does 2d8 damage, requires a hit, then makes enemy to save or poisoned. On comparison magic missile does automatic damage averaging greater than it.
Oh and blade ward is pretty horrid. If you use it you get half the damage, but you haven't progressed in your own goal, which is kill the enemy.
