You may call one of the four types of Elemental spirits that
the forces which they control may be brought to service in
your favor. Their powers maybe known by their elements -
Sylphs bring winds and storms, and carry messages.
Undines bring floods and will comfort the weary.
Gnomes bring earthquakes and establish or destory stability.
Salamanders inhabit flames, and will purify any with pain.
The command to the elemental spirits is given along with a
casting of a certain substance (pleasing to the elemental) into
the body of material from which the elemental will manifest.
The active elements' spirits (fire and air) receive a
combination of fiery and airy materials, and the passive
elements' spirits (earth and water) receive a combination of
watery and earthy materials. Thus would one give incense to
the Sylphs, black powder to the Salamanders, soft clay to the
Gnomes, and water with river silt or beach sand to the
Undines.
It is wise to use a Protection spell when performing the
conjuration of an elemental spirit.
