Hermetic Theurgy

Hermetic Theurgy is a Minor Mystery Virtue. The first and critical mystery in the theurgic mysteries, it teaches how to summon named spirits. Practitioners of Hermetic Theurgy can summon spell spirits to allow them to create the effects of the spells without needing to cast the spells themselves, and can invent and cast theurgic invocations to summon aspects of daimons and bargain with them.

Note that magi not initiated into the mystery can still utilize theurgic invocations, albeit with more difficulty - but cannot invent them.

It has been noted in the fan community that it is entirely reasonable to use True Names and ordinary Rego magic to summon and control spirits with powers comparable to spell spirits. Such spirits also tend to be more flavorful than the mechanical "spell spirits" hermetic theurgy introduces, but their availability and statistics depends on the story guide. The invocation of daimons can likewise be deemed to be perfectly within the purview of standard Hermetic magic.
