You're already on the right path with your limb extensions.

I'm an Indogene. An artificial person created to pursue science. My kind have research focuses- mine was medicine and repair. Clawdits are shape-changers, so an arm that can alter shape with the victim would be most optimal.

I'll send you a thorough proposal.

Speaking of which, I could use more medical information on Gems when you have a chance. Right now I have very little.
