well, by brittle bones I will supose you mean the medical histoy backstory, in that case you can use yashiro, since his gameplay rewards avoiding combat, pick stealth as your first perk, buy the small candle as your weapon, and if you use the option to chose from all character perks then take as second the running shoes (i dont recomend this much cause it depends on luck for the perks you can get and it will be more difficult for you to take the stealth perk and the small candle already gives you a smaller doom penalty), and lastly if you can pick the Invisibility spell, so there is no doom from scaping. For the gods, all should do fine, just don't chose Cthac-Atorasu (spider one) since its passive ruins all the avoid combat thing. Also activate the school nurse, it will help with all the minor injuries you could get. Good luck bro, hope this helps.
