Successfully complete the story, then start a New Game+. Travel to the Amiibo Scanner (large green orb) in the Monastery. Interact with it and scan an amiibo to unlock rewards. Scan any Fire Emblem related amiibo to unlock a secret chamber where you can find Sothis and a map. Talk to Sothis to unlock a spell for Byleth that gives them a +7 Resistance buff. The spell can be used once per battle. Any of the following Fire Emblem amiibo work: Marth, Ike, Alm, Tiki, Celica, Robin, Lucina, Roy, Corrin (Male), Corrin (Female), and Chrom. Each of the Fire Emblem amiibo also unlock a classic battle theme from previous games.
Successfully complete the indicated task(s) to unlock the corresponding class. There are three basic requirements for each class —- must be a certain level, have a certain type of seal, and certain skills available to help your characters pass the certification exams.
Commoner: No requirements. Starting class.
Dancer: Send a character to the White Heron Cup and win the event to immediately unlock it. The White Heron Cup event unlocks on the first day of the third week, on Chapter 9. To unlock the event participation, explore the first week and talk to Rhea to get a quest. Only students can participate. After accepting Rhea's quest, talk to any student before or during the second week of the month. You can select to make them your representative -— you need to select a rep before the third week begins. To win the cup, have a high Charm stat. To increase your Charm, talk and choose to train your representative. This will begin a Dance Practice session —- you will get +5 Charm each time you do this. You can only do this once per week. Training is important, as it is recommended to have approximately a 13 Charm stat to win. If you talk to Manuella, she will tell you the secret of the White Heron Cup. It is still possible to win with a lower Charm stat. To increase Charm even higher, cook a meal that gives everyone in your class +1 Charm. On the day of the White Heron Cup, each class representative will dance. Three judges will select their favorites. As long as two judges select your representative, you will win. The Dancer class is a specialized class, and you can switch to it when you select to re-class your unit.

Recruit any student
It is possible to recruit any student with at least B-Support status. It may take several tries, but you can save the game and try again if it fails. To increase a student's support status, even if they are not on your team, there are a few things you can do. Buy them flowers on their birthday, gift them flowers from the garden, take them on battles by requesting their help, or invite them to meals. The best and easiest way is to simply give the student you want to recruit lots of flowers. It requires approximately 30 flowers to reach B-Support. It does not matter how low your stats are —- students with B-Support can be recruited. You can have "E" level skills in everything and still get any students on your team. When a student is at B-Support or higher, they will randomly ask to join you. It will not happen every weekend -- so reload your save file and retry weekends until the student finally offers to join. It is possible to recruit multiple students per month using this method, but do not expect to recruit more than one a week.
