Finally got around to playing around with a monk, and noticed that spirit does not regen with fists of thunder unless actually attacking a monster. So it's impossible to regenerate spirit by punching in place, or even punching barrels and stuff! Is this by design, or a serious bug? Currently only lvl 8 HC, so perhaps later spells work properly?
monks donot have a base spirit regeneration. They should make the healer in town able to fill it though because its pretty crappy when transitioning and you have zero spirit after a trip to town. I suggest using the chant of resonance passive when you get it and keep a mantra active, that seems to keep it up for the most part. there are also many other ways to fill your spirit when you get higher level.
