Inside the Unova Battle Institute
The Battle Institute (Japanese: トライアルハウス Trial House) is an area for the player to participate in mock battles. There is one Battle Institute in each of the Unova, Kalos and Hoenn regions.
The Trainers met here are the same ones found in the Battle Subway and Battle Maison. The player can opt to fight five consecutive battles—called the Battle Test—of either Single Battles (requiring three Pokémon) or Double Battles (requiring four Pokémon). When battling, all Pokémon temporarily become level 50. Bag items are not permitted to be used. At the end of the fifth battle, the player is awarded a score and a rank. Depending on their score, the player will receive a certain amount of Battle Points and a vitamin. Unlike the Battle Subway and Battle Maison, the Battle Institute does not require the player to save the game before participating.
Each battle grows in difficulty, starting with pre-evolved Pokémon and potentially fighting Legendary Pokémon by the end. Once the Battle Test begins, there is no quitting; losing one battle means continuing to the next, until all five battles are complete. The 'Run' command acts as a battle forfeit measure for that battle only. If it is not the fifth battle, the player's forfeit will trigger the next battle.
In Generation V, it is found in Nimbasa City; in Pokémon X and Y, it is located on Northern Boulevard in Lumiose City; and in Pokémon Omega Ruby and Alpha Sapphire, it is located on the west end of Mauville City.
In Black 2 and White 2, the Battle Institute can only be accessed after defeating the Elite Four and Champion. If the player tries to access it before that point, an Ace Trainer will exit the institute and block the entrance, telling the player that they must become the Champion before they can enter.
Each battle increases the maximum points that can be earned, meaning the max amount of points one can earn in the first battle is lower than the max points one can earn in the last. Points are awarded depending on how many battles are won (no points are awarded for lost battles) and how well the player beats the opponent; fainted teammates count against the final score, as does damage taken.
The scoring breakdown is as follows:
- 1000 points per battle won
- 80 points per opposing Pokémon fainted
- 5 points per switch
- 1 point per super-effective attack
- 4 points per opposing attack that is rendered ineffective (either from type immunities, Levitate, or a status attack that the Pokémon is immune to due to its type)
- 2 points per opposing attack that is rendered not very effective
- 30 points if a battle was won with the opposing side taking at least one turn, 15 points if a battle was won without the opposing side taking a turn
- -80 points per Pokémon fainted
- -10 points per turn
- -10 points per ineffective attack against the opponent (on the same basis as the above)
- -2 points per resisted attack against the opponent
- 1 point per percent of HP remaining after each battle
