Summoning

At 2nd level, you gain a familiar, as a wizard equal to your archivist level. Your archivist level stacks with any wizard levels you posses when determining the powers of your familiar.

Conjuror’s Blessing (Su)

At 14th level, you increase the duration of your creation (summoning) scripts by a number of rounds equal to your Intelligence modifier (minimum 1). You automatically treat all creation (summoning) scripts you cast as if they were overloaded with a single runic charge of your choice; this is in addition to any charges you overload normally. At 18th level, you instead treat these scripts as being overloaded with two runic charges of your choice.
