You will explore the bases having double battles with high leveled grunts. Last battle is against Tabitha/Courtney or Shelly/Matt respectively, if you win you get 1 random rare item as a prize and then they kick you out. If you win 6 base invasion in row, your final battle is solo against Maxie/Archie who will use Groudon/Kyogre and a more challenging team. Winning this will prize 3 random rare items.
