Okay, fair enough - I'll throw something more specific out there - a provisional idea, but easier for you all to react to a concrete proposal.
New Rego Corpus spell guidelines
- Level 20: Grant a +1 bonus to a character's Living Conditions modifier.
- Level 25: Grant a +2 bonus to a character's Living Conditions modifier (with an Intellego requisite).
- Level 30: Grant a +3 bonus to a character's Living Conditions modifier (with Intellego and Creo requisites; must be a Ritual).
I was thinking Minor Breakthrough as well; I don't know if a single Minor Breakthrough would encompass the whole trio of new guidelines or just one of them.
Example spells
Therapy of the Medicus
Rego Corpus 35
R: Personal, D: Moon, T: Individual
The caster's bodily humors are regulated in a way that helps to avoid diseases and ill health, as if she were a patient under the care of a doctor. If the caster is under the effect of this spell for more than half a year, she gains a +1 bonus to her Living Conditions modifier; note that this does cause Warping as a continuous effect. A character may be affected by both this spell and an actual doctor's regimen, but only the larger of the two bonuses applies.
Regimen of Salerno
Rego (Intellego) Corpus 40
R: Personal, D: Moon, T: Individual
As Therapy of the Medicus, except that the Intellego requisite increases the ability of the spell to regulate the humors well, granting a +2 bonus to the Living Conditions modifier.
Wizard's Eucrasia
Rego (Intellego, Creo) Corpus 55 (Ritual)
R: Touch, D: Year, T: Individual
The target's bodily humors and faculties are regulated and amplified in a way that helps to avoid diseases and ill health, as if she were a patient under the care of a highly skilled doctor. If the target is under the effect of this spell for more than half a year, she gains a +3 bonus to her Living Conditions modifier; note that this does cause Warping as both a powerful effect (unless designed for or cast by the target) and a continuous effect. Characters affected by this spell cannot also be benefited by following an actual doctor's regimen.
I don't think these spells should require Finesse rolls (certainly not any spells with Intellego requisites). I kind of WAGged the spell guideline levels, based on what I thought the final spell levels should be; but it did fit reasonably nicely as being higher than the existing Level 15: Direct the flow of bodily energy.
