The very first legit summoning I did wasn't great, a 4 star Palla and then I think a 3 star Fir, Azama, and Jakob? Then I rerolled and ended up with 5 star Leo, 4 star Jakob, and 3 star Shanna + Oboro, which I kept.
Far more disappointing than either of those is that it only ever gives me 1 green orb at a time (if any) and its always Cecilia...
