How much pain can your muse withstand?

They can handle most of being burned alive pretty okay. Towards the end they pass out rather than feel a whole lot. Additionally, they can deal with wounds from sword injuries are gun shots okay – but it’ll be obvious that they are hurt. They’ll just continue at least until they get to a point where they need to withdraw. 

So they take about an average about of pain and would be able to work through it for some time longer, if something required that.
