How does spellcasting account for targeted attacks ? Should a target be so big that you can only reasonably make a quick attack on its leg or when trying to snipe the wings of a flying being, if both cases use sensory range, does that impose a specified target penalty ? Does a similar penalty apply only when trying to hit with an aimed spell ? Similarly, if only part of a giant target is hit by an area of effect, are only those specific limbs attacked or is the subject entirely unaffected ?

Is the targeted body part its own supernal symbol which can be used to target that precise thing?

Like does a 'wing' have a meaning which allows it to be targeted by a spell?

Are there any spells which use part of a target as the subject?

There is no reason to ever do a targeted attack with aimed spells. If the spell hits, it affects the subject. An aimed spell hitting the subject's arm would still inflict a Leg Wrack if that's the effect of the spell.
Targeted sensory range spells doesn't make any sense.

Book doesn't say how to handle subjects that are both inside and outside an AoE. But for subjects that are so large that you can't cover them with an AoE, they'd absolutely not be valid subjects since they obviously outclass the Scale factor. (Spells like "fill this AoE with fire" still fills the area with fire which may affect anyone who's wholly or partly within the area.)

If a spell is cast on a subject, it needs to have enough Scale factor steps to accomodate for the subject's Size.

I don't think that is in question. The only question is what size is the subject's mind.

Eg: does an elephant have an elephant sized mind?

In general, nothing has an outright immunity to any single Arcanum. It's all about the specific spell effects. Most Mind spells won't have any effect at all on those as long as they don't have any minds, but some Mind spells doesn't affect the subject's mind and can affect those just as well as a human subject.

Can you give an example?

Like take Psychic assault "A living mind is a delicate thing, easily broken... The subject takes bashing damage equal to Potency."

As read, the Elephant Zombie with no mind, as a subject of this spell requires Scale and takes bashing damage. Or their mind is the Subject, in which case it has none and can't be affected, (or perhaps with conjunctional mind/ghost possession - it has a kind but it is this ghost/goetia which is the subject* and it doesn't necessarily have the scale of an elephant?)

Alternatively, Can you cast grant skill on a Golem to give them new "fields"? I can't think of any other listed Mind spell which you could use on a mindless Zombie...

*This seems like a distinct case, where the possessing ephemeral entity has their own health track. Right?

Speaking of size. Is there any concensus on how Mind affect large animals/monsters?

Eg: a size 7 horse, does it require extra scale for large target? Does Life and Mind treat it differently?

If a spell is cast on a subject, it needs to have enough Scale factor steps to accomodate for the subject's Size.

Likewise, do Zombies, Golems, Eidolons and similar have no mind (without the addition of a mind 5 conjunctional effect) and are thus impervious to Mind effects (with the possible except of possession)?
