Hey, nice idea but how is this supposed to work?

Imagine Cat hides and moves with stealth. Obviously Joy needs to know her position. So Ashley and her summons gotta act as if they don't know where she is? 

Not sayin it can't be done, it's essentially the same as fighting NPCS controlled by, the DM, but you can't deny Ashley has an advantage on the information side.

And does Ashley regain full health during transformation? I guess so. I know what I would do but I'm not playin. Surprise me guys, don't be lame!
