Stat her, good hunters.
What class does she belong to, if at all any?
Commoner. Now return to /v/.
She's a non-combative construct with special abilities based around empowering others.
The person she's based on is the one with actual class levels.

A basic construct, with admittedly some talents that let her train and improve hunters she works with.
Useful, helpful, but meek.
The superior is clearly the original, though the doll has its place.
>>50193333
The doll doesn't use class levels. She's clearly a CR35 Aberration.
>>50193333
Level 20 Waifu
>>50194050
this is the correct answer
More seriously though, in game terms the doll is immortal but non-combatant. She'd probably be treated as a mechanic more than a character (i.e. there'd be rules for how interacting with the doll works and what affects the doll's actions have but no stats in the standard sense)

Is she even attackable?

She is, and she can die, but she simply returns the next time you appear in the Hunter's Dream.
