Just strikes me, but the radiances and beams seem to be massivily different in power from each other. See, in the beam section, you have various save or sucks and "Deal 1d4 cold damage per illumination bonus" which is like 4d4 at the end. So, petrifiy one opponent for four rounds on a failed save, or deal absalutely pathetic damage?
Now this is the kind of critique I need! Thanks! I was worried about that kind of thing. That's why I said that I was considering restricting some to higher level glowherds. Do you think that I should do that or try to balance them better? If the latter, I'd probably need help deciding which should be powered up, which should be nerfed and which are ok.
