So I am making a Barbarian for an up and coming module, and found a particular combo of two things already good for Barbarians, and am wondering if this is as good as it seems. I want to take human for superstition bonuses as well as Heart of the Fields. However, with Allnight it seems to get very strong. With Allnight I am immune to fatigue for 8 hours, more than enough for a day, meaning I can Rage cycle all I want, without investing in Oracle levels, or waiting until level 17. At the end of this I am exhausted, but using my alternate ratial trait from being human Heart of the Fields, I can ignore this completely. Allowing me to do it for another 8 hours if I like, or sleep unimpeded. Seems like a fantastic option, is there anything I am missing?
