Though I like mystic knight and magic archer as versatile units. The knight's great cannon and ruinous sigil are incredible abilities, then adding in burst strike is awesome The magic archer is amazing against things with it's hunter arrow and 6fold arrows, especially bosses where it has like 10 points to target and then dagger flurry hundred kisses to slaughter them.. The light arrow is awesome too at night, no need for lanterns
My augs are all HP up, stamina up, reduce physical damage x2 (lol, does *** all), HP regen then.. I think expanded field of vision, which is kinda pointless seeing as enemies doen't show on the mini map but oh well, augs don't seem that amazing really most of the time.
