Hello, thanks for playing the game !
I have a doubt for the left path with the build you were playing but the middle and right could be passed. I updated the game after the jam ended so the right path is a bit easier now and left should be ok too. Killing the dragon makes the path really easy afterward but you have to have the highest power with heroism and having just enough food (a hunter works best there).
So basically left path still requires high power and a bit of holy, middle path is all about slaying the dragon, right path can be passed naturally but fire cloak makes it easier.
