Special Training Boosts (特訓)

Special Training Boosts (特訓) (とっくん "tokkun") are special boosts you can give players to their Basic skills.

If you use players, the higher rank the player, the higher chance of upgrade success. The chance also increases exponentially if you use a player who is at its maximum Player Experience Level (選手レベル).A Special Training Coach (特訓コーチ) of any rank can be used to upgrade. They are only S, A, and B rank. A Limit Breakthrough Coach (限界突破コーチ) can only be used with a player of the same rank (S-Rank Coach with S-Rank Player)

Important! Using players means you lose that player once you attempt the upgrade, even if you fail.

If a player can get a Breakthrough Upgrade (限界突破) using the same player with the same rank (or the rank below at Maximum Player Experience Level (選手レベル), then that player will appear first.

You can use the Player Filter (表示切替) to search for appropriate players.

''Tip: Maxed out B-rank players are very good to use for this. Maxed out A-Rank players you might want to save in case you get an S-Rank player of the same name''
