I just woke up my Serperior in Black 1 cause I was done in the Dream world and it said Seperior has gained 1 level. Does this usually happen? Cause it didn't happen any of the other times.
Yes it happens when you gain a certain amount of Dream Points
Edit:
If the player earns 500 points between tucking the Pokémon in and waking it up, the Pokémon's level increases unless the Pokémon is already at level 100.
