Nystul's Grue Conjuration (Conjuration/Summoning)

Level: 4
Range: 60 yds
Duration: 3 rounds/level
Components: V, S, M
Casting Time: 1 turn
Saving Throw: None
Area of Effect: Special

Explanation/description: This spell, which is actually a
group of four risky spells, will summon one grue-harginn,
ildriss, chaggrin, or varrdig-from one of the four elemental
planes:

Air-Incense
Earth-Soft Clay
Fire-Sulfur
Water-Sea Water

These material components must be used when summoning
the grue desired. The type of grue to be summoned
must be decided before the caster memorizes the spell.
Grue are notoriously untrustworthy and difficult to control,
so the caster must rely on more than just concentration
to keep the grue under his command. As soon as the
grue is summoned, it will demand a payment from the caster
for its service. The payment offered must be at least 500
g.p. worth of goods of interest to the grue, or the grue will
be angered and immediately attack the caster. If the grue
is satisfied with the offer, it will grudgingly perform one
service for the caster for the duration of the spell. The grue
will try to subvert or openly disobey the caster’s orders if
the grue finds them unpleasant.
