Battle Tower Crystal · Johto landmark

The Battle Tower is reached through a gate on Route 40, the beach west of Olivine City, and is unique to Crystal. Trainers enter a Battle Room with three Pokémon and face seven opponents in a row, drawn from 70 trainers across 31 classes, for a stack of stat-boosting vitamins.

Tips
- Rules: exactly three Pokémon, all different species, no two holding the same item, and no Eggs.
- You choose a Battle Room by level in steps of ten; no entrant may be above the room’s level, and Mewtwo, Mew, Lugia, Ho-Oh and Celebi cannot enter rooms below L70.
- Beating all seven trainers in a room earns five of one vitamin chosen at random: HP Up, Protein, Iron, Carbos or Calcium.
- The game saves before you enter; to stop mid-challenge you must save, or the room challenge cannot be resumed.
- Opponents use teams of three, so a balanced trio with varied held items handles the random pool best.
