How do I raise the Black Entree level in Pokemon White 2? Or is it even possible? Please let me know ASAP!
As the Entree grows, it spirals outwards and its color changes according to the composition of its ★Black and ☆White levels. Growth of the Entree may only be done by completing missions in other players' worlds.
You must complete entralink missions in other player's worlds.
Hope I helped! Source
