I'm playing around with spirit magic ideas and have two queries.
We have the canonical minor virtue of commanding spirits in Legend of Hermes (one of Fortunatas mysteries). Would this apply to a spell to summon a spirit. I mean you are effectively commanding a spirit to come to you. But on the other hand, the spell guidelines have command and summon as two different things. Would you allow it to apply to wards against spirits (commanding them not to pass), bindings (commanding them to stay put) or would you define this much more restrictively? Could it go the other way and apply to almost any rego spell affecting a spirit (since magically you are controlling it in some way).
HoH:S under the Tytalus section has the spell Coerce the spirit of anger and the summon the spirit of anger. These spells do exactly what it says on the tin. This implies you'd need a different spell to summon/coerce a spirit of lust, then another for duty, and so on and on. My impression from the main guidelines in TMRE though is that a single spell of Rego Vim should be able to command any magic realm aligned spirit (with obviously a similar spell to summon them). Which is correct? The titanoi version implies a spell for every different type of spirit and is useless when your spirit master encounters a spirit of a different type, whereas the TMRE version seems more as intended. Can anyone shed some light here?
