Developing spells feels like an option? Although with LLSM Viola probably could do some things on a temporary basis with sponts.
Viola has a Mu(Fo) lab total of Te 12 + Fo X + Int 4 + MT 8 + Aura 5 + Lab Mu Bonus 1 + Familiar 8 +IG 3 = 41 + Form
The most obvious Animae to create given what we're trying to do are Animal or Herbam ones.
- Muto Animal is base 10 to change an Animal into a Faerie (so 10 + 1 Touch + 3 Moon + Might would be level 30 + Might), whilst her Animal score is 8, so a score of 49. She could slightly bump that up by involving Chryse (only +1 currently) or experimenting (IG +3 + die), but not to the point she could reliably invent the spell in a single season. In two seasons she could create a level 32 spell, which is only a 2 Might faerie (3 if she involves Chryse) but it probably doesn't need to be particularly powerful for our purposes. If she did go down this route, it probably makes most sense to make bird Animae of some kind.
- Muto Herbam is base 4 to change a plant into a Faerie, so a level 20 + Might spell. Viola's Herbam is 6, so she has a MuHe score of 47. That's comfortably enough to invent a level 23 spell in a single season (24 if she involves Chryse). The downside of a Herbam faerie is that it's likely to be significantly less mobile than an Animal faerie, so she's probably have to plant them in situ, and come up with a way for them to communicate back to her.
The other problem with Animae is the question of control over what Viola's getting (and then the need to bargain something with it to get it to do what it wants). This has been discussed before on the boards (e.g. Animae: Thoughts on How to Use in Practice - #2 by Jank) - in that thread I suggested allowing a Formulaic spell to produce a consistent result, and for the Maga to be able to have a broad goal when designing the spell (as presumably testing whether it's doing what she wants is part of developing the spell), but not to be able to determine an exact stat block.
