Summon Least Yugoloth

Using this spell, a wizard can summon a least yugoloth guardian to protect something of importance. The yugoloth is under the wizard's complete control, and will obey commands of its master even after the master's death. The yugoloth must stay within 90 yards of the charge or be subject to fits of scaring-ultimately lethal-pain.

The most important component for the spell is the true name of the individual yugoloth to be summoned. Finding such a name is a difficult task, and only through exacting research or dark pacts with other fell creatures can a wizard obtain a least yugoloth's name. The material component is a ruby worth at least 500 gp, which is destroyed in the casting.

The reverse, banish least yugoloth, will send a least yugoloth back to its home plane. If the creature's true name is used, the banishment is automatic. If the true name is not used, the creature receives a saving throw vs. spell at a -2 penalty against the banishment.

The material component for the banishment is a pinch of powdered silver mixed with holy water.
