Not all who summon spirits do so for personal power. Some are more than willing to use occult creatures to do their bidding, bargaining with the spirits in order to gain minions to carry out their ends. The spirit caller is such an individual, a master of altering pacts in order to gain powerful creatures to serve them.
A spirit caller does not summon an eidolon as most summoners do. Instead, a spirit caller binds spirits, exactly as an occultist. The spirit caller’s binder level equals the character’s summoner level, and a spirit caller binds spirits as an occultist of that same level. On a successful pact, however, the spirit departs the seal, leaving the spirit caller with only the ability to manifest and suppress the spirit’s physical sign, as well as its influence if the spirit caller made a poor pact with the spirit. However, whenever the spirit caller shows a spirit’s physical sign the spirit caller gains that spirit’s vestigial companion, which manifests in a space adjacent to the character. The vestigial companion has access to all of its spirit’s granted abilities except the one that must be traded in order to gain the vestigial companion.
For example, in order to gain Aza’zati’s vestigial companion, a binder must replace the smaller is better granted ability, so the spirit caller’s vestigial companion to immediately disappear. If the vestigial companion is called back by showing the spirit’s sign once more, it returns with the same hit points, ability damage, and conditions it suffered when it was last present. Time spent with the spirit’s sign hidden counts against the duration of any spell effects that the vestigial companion might have been benefiting from, as well as how many rounds the spirit’s major granted ability is expended. If the vestigial companion is slain, a new one cannot be summoned until a new pact with a spirit is made.
The vestigial companion only exists while the spirit caller shows the spirit’s sign. Suppressing the spirit’s sign causes the vestigial companion does not possess this ability either.
The spirit caller cannot bind spirits whose vestigial companion is not an animal companion, familiar, eidolon, mount, or similar creature. Even a multiclass spirit caller suffers this restriction. The vestigial companion uses the spirit caller’s Charisma bonus and binder level when determining the benefits of granted abilities. The vestigial companion is treated as an eidolon for the purpose of how spells, class abilities, and similar effects interact with it. This ability functions as bind spirit for the purpose of qualifying for feats, prestige classes, and similar abilities.
This ability replaces eidolon.
Whenever a spirit caller makes a good pact with a spirit, the spirit’s vestigial companion gains a number of evolution points equal to half of the difference between the spirit’s binding DC and the spirit caller’s binding check result, up to a maximum number of evolution points equal to half of the character’s summoner level. The spirit caller can use these points to add evolutions to the vestigial companion as though it was an eidolon. The vestigial companion has a base form that most closely resembles its actual form for the purpose of meeting the prerequisites of evolutions.
This ability replaces summon monster.
