I think it not even guidance well for me anyway... each time i reloaded trying to save Arabella.....it always falled me..... I reloaded the game 13 time and each time i have different target to pass and I failed all 13 time....with the same character buffed with guidance and sometime just not with guidance. Sometimes I would need 10 to succeed never secceed the roll and other time it would ask me for a 17-19 or even 20 to suceed in saving the girl.
