I don't remember much of my other units in my Lunatic game, but the unit that stands out the most is my MU and Lissa
I went Def+/luk- for some reason and still managed to max out my str and res before my def, needless to say the Lunatic run became pretty much a cakewalk. I am going back to str+ next.
On the other hand, Lissa receives only 1 stat for 3 different levels, her normal levels are rather unremarkable as well...I feel bad that I might have to bench her considering how well she did in my first game, but RNG is a cruel mistress.
