Level: Demonologist 3, Mortal Hunter 4, Sor/Wiz 5
Components: V S, Soul

Effect: 2d4 dretches
Duration: One year
Saving Throw: None
Spell Resistance: No

The caster calls 2d4 dretches from the Abyss to where she is, offering them the soul that she has prepared. In exchange, they will serve the caster for one year
as guards, slaves, or whatever else she needs them for. They are profoundly stupid, so the caster cannot give them more complicated tasks than can be described in about ten words.

No matter how many times the caster casts this spell, she can control no more than 2 HD worth of fiends per caster level. If she exceeds this number, all the newly
called creatures fall under the caster's control, and any excess from previous castings become uncontrolled. The caster chooses which creatures to release.
