You must increase your Secret Base rank to Silver first This can be accomplished by stealing over bases flags (100 flags to obtain silver rank) that you encounter via StreetPass or PSS and afterwards, your Secret Pals (other Secret Base trainers you've invited to your own base) have the ability to give you a max O-power Source: Linkity Link
When you have reached Silver Rank in your Secret Base, you have the ability to receive MAX Powers from your Secret Pals. These have the same effect as Level 3 powers and last for 1 hour. They cannot be used by other players through the PSS
