Получается после победы над последним боссом.

Трофей можно пропустить.
Перед финальным боссом, а точнее перед ивентом “Go Meet Luard”, нужно создать Philosopher's stone,
рецепт которого открывается после получения 45 уровня алхимии (При условии если у вас уже есть последняя 5-я книга с рецептами, где этот рецепт и находится).
Трофей выскочит во время ивента "Let’s Return to Our Atelier”, идущий после сюжетного трофея After a Battle".

Легкий трофей.
Максимальный уровень дружбы - 100.
Трофей легкий в том плане, что в отличие от других частей, здесь уровень дружбы повышается вне зависимости от того, кто у вас в команде. Все до единого пассивно повышают уровень при сборах и битвах на различных локациях.
Стоит учесть, что уровень перестает повышаться если он дошел до точки ивента друга.
Это можно проверить в меню статуса персонажа.
Если уровень красного цвета, значит в наличии ивент.
P.S.: Помимо ходьбы, можно повышать уровни подарками, но на своем личном опыте могу сказать, что это не так уж и необходимо.

Рецепты нужно только открыть, необходимости создавать после этого предмет нету.
