Conjure Spirit
As he once bound the least of spirits as spies and aides, so may a koldun with this ritual call more powerful spirits. Such creatures answer proper beckoning and oblations of blood, which needn’t come wholly from the caster. They do not make pacts — they trade favors. The koldun must pledge something of value to the spirit, which may seem trivial to human or vampiric notions of worth. If the spirit likes the offer, it awaits the price. Should it find the price reasonable for the service provided by the vampire, it drinks the blood and goes about its new business. It does not bargain or haggle, nor does it deign to listen to threats. If the vampire insults the spirit with a poor offering, it will not remain to continue bargaining; it simply vanishes to wherever it belongs and leaves the vampire with a pool of cooling, untouched blood for his trouble. Thus, it behooves a koldun to learn the proper etiquette for dealing with beings of such power.
System: A successful casting draws the attention of a spirit as described. The statistics of a nature spirit summoned with this ritual are left to Storyteller imagination but should greatly exceed those of spirits called with Rouse the Elemental Spirit and even the caster in extreme cases.
