What changes in each facility

The Tower is the baseline streak challenge. The Dome shows opposing teams before each four-round tournament. The Palace lets a Pokémon’s nature choose its actions, while the Arena judges Mind, Skill and Body if neither side wins within three turns.

The Factory replaces your party with rentals and lets you swap after a win. The Pike hides battles, healing, wild encounters and status traps behind seven-room runs. The Pyramid gives you a special Battle Bag and gradually lights each dark floor as you defeat Trainers.

Earn and spend Battle Points

Completed streaks award Battle Points. Spend BP at the Exchange Service Corner on hold items, vitamins and decorations, or use it for repeatable move tutoring. Frontier Brain victories pay more than ordinary sets.
