(Spell Compendium, page 123, DnD 3.5)

Necromancy

Level: ; Druid 3
Components: V, S, M
Casting Time: 1 standard action
Range: Touch
Target: Creature touched
Duration: 1 round/2 levels
Saving Throw: Fortitude negates
Spell Resistance: Yes

You touch your foe with the dust of dead flies on your fingers, giving birth to hundreds of writhing maggots in his flesh.

With a successful melee touch attack, you infest a creature with maggotlike creatures. If the touched creature fails a Fortitude saving throw, the magical maggots deal 1d4 points of Constitution damage each round at the beginning of your turn. The subject makes a new Fortitude save each round to negate the damage in that round and end the effect.
The infestation can be removed with a remove disease or heal spell.

Material Component: A handful of dead, dried flies.
