Take the tour ×  I've unlocked Challenge mode by beating the
champion in Black 2. If I unlock it for a friend what changes
exactly? Bulbapedia wasn't very specific, just mentioning that
the AI becomes more challenging, higher level Pokemon, and more
held items.    • Are the changes universal or limited to mostly
important NPCs (gym leaders, Team Plasma leaders etc)?   • How
does the AI improve? Does it swap Pokemon more often or is it
mostly better move choices?   • Are all the Pokemon in the game
higher level or just the trainers you battle throughout the
game?   • What sort of held items does it unlock for the enemy?
Does it increase the chance of wild Pokemon having a held item?
