Tips

 * As Spiritomb has a chance of dropping an Odd Keystone, it is recommended to have some way to enter walls, if it were to drop from a defeated Spiritomb in a wall.
 * It is recommended that you bring a Pokémon with Safeguard or Refresh to protect against all of the status moves here.

Trivia

 * Floor 17 of Tanren Basement has Rotom appliances foreshadowing the fact that Rotom only spawns on Floor 17.
