Morph: Turning into a Ring and similar, small inanimate objects...

[Alqamar]

Hello there:

I'm designing a shapeshifting power based on the core advantage Morph, with the following features:

1- User can only turn herself, not other people (Morph advantage)
2- User can only turn into inanimate objects (Unliving Forms Only, 0%, Powers, pg. 75)
3- Improvised Forms (+100%, Powers, pg.75)
4- Flawed (-10%, Powers, pg.75). This represents how rings-that-are-characters look slightly odd...
5- User can turn into anything smaller than a Human sized-being (SM 0)
6- User keeps his IQ. ST, DX and HT become the corresponding values for an inanimate object of an appropiate size and material.
7- User loses most Senses, becomes a Portable object (Legless with the Portable limitation), and gains most benefits of being inanimate (No need to Breathe, etc...)

My question is: Do I need to add the Shrinking advantage? Or is it enough to create 'racial templates' for inanimate objects taking into account negative SM, etc...

I don't want characters with this power to be able to become smaller at whim. They can only become small objects, not small humanoids.

I don't think you need Shrinking. In fact, not taking Retains Mass seems to imply freedom of changing size.

I would say that just making it a "racial" package with a negative SM is viable. You may want a superscience explanation (link to a sidereal aspect of our universe where mass is virtual rather than actual, etc.), but that's already covered by Shapeshifting without "Retains Mass/Size".
