Setting Q&A - Familiars, Wishkin, and Exalted Wishkin

[The Nottest of Daves]

NOTE: This thread will be merged into the main Setting Q&A once it is fully reconstructed

Coming from the aftereffects of [UNDEFINED] and the great Reality Glitch, I have a new character: Willoughby the Atomikitty! However, her subtypes are things that have yet to be seen in focus (that I am aware of, at least): Familiar and Exalted Wishkin.

So, I have a few questions about exactly what these entities go around doing, how they do those things, and what they look like when doing them.

1. What do the most common kinds of familiars look like? Are there major differences in appearance between caster types (a Witch's familiar vs a Wizard's familiar vs a Magical Girl's familiar, etc)?
2. What are the base powers of familiars? What classes have ability trees that can boost or expand those powers (and are those trees statted out)?
3. What does a standard Wishkin look like? What classes (outside of their entity class) help boost their base powers?
4. What is the difference between a Wishkin and an Exalted Wishkin, beyond the second having a deity effect? Is there a significant power differential between the two if they're at the same Level? Does the gap widen as the comparative level increases?

For reference, the Subtype-descriptions:

Familiar - Mahou Shojou
This is a downright weird class, Its main abilities have nothing to do with its subtype, with its actual entity-subtype getting most of its powers in a mix of classes that primarily involve Wizard and Beastmaster, while the class itself deals more with Wands and special activated abilities for entities that can get boosts from (but don't have to have) allies of its subtype (but with said main part of the class also requiring significant investmentment / cross-mixing in other classes, most notably Sorceress and Wizard)
Training/Summoning/Pet Aspect: <None Stated>
Being-The-Entity Aspect: <None Stated>


Wishkin - Wishmaker
A Good aligned planar subtype that may at some point replace Angels; currently excessively rare. Born from wishes, hopes, and dreams; a type of quasi-tangible spiritual being whose presence reshapes reality who guide those with pure hearts towards kinder fates than they might otherwise possess
Training/Summoning/Pet Aspect: Action-replication without summoning
Being-The-Entity Aspect: Buffs, Healing, Delayed actions, Dodge bonuses, Resurrection


Exalted Wishkin - Wishmaster
Like Wishkin, but more powerful and with a Deity Effect
