Thanks everyone for your replies.
I will have the Glass Golem magically heal naturally, so no need for repair. And I'm using hit locations in the game, so I will be using the hit locations for the golem to. I like the idea of it either shattering or doing nothing.
Oh, and the player wanting this character is a women.
This is her back story " character was a noble from an important family a century or a few centuries earlier in a civilization that since disappeared/ moved from the area because of invasion, natural disaster, whateva. she was beautiful, rich, flighty, and desired, a spoilt brat basically
she attracted the eye of many suitors, and had many secret lovers, though she had been engaged at a young age. One such lover, obsessed and jealous, devised a way to keep her captured forever after the official announcement of the engagement and subsequent marriage was made public. so he kidnapped her, killed her, and placed her soul in a glass sculpture made exactly in her likeness, sustained by a magical flame which gives her movement"
Probably have her introduced by the other characters finding her in a form of stasis.
