Hi, I just had this duel with Leo Lv 29 against Luna Lv 10 at the gate to fulfill the mission battle against Luna on stage 27. After winning Leo got +0 exp but went straight up to lv 30, but that would have needed at least 5000 or more exp. Did someone else had this, too?
That's normal. You were probably 750 XP (or 2250 with 3x rewards) away from lv30.
