White Heron Cup

The White Heron Cup is an event that occurs during Part I of Fire Emblem: Three Houses. It is the only opportunity in the game for a character to acquire access to the Dancer class.

Overview
The White Heron Cup is an annual competition between students of the three houses of the Officers Academy. Byleth is asked to optionally select a student from their chosen house to participate in the competition. Victory in the competition is determined by the competitor's Charm stat, and Byleth is granted one opportunity to put the competing student through a training session that will grant the student a permanent Charm boost. All members of the three houses are eligible for the competition. Should the student Byleth selects for the competition win, they will gain the ability to reclass into a Dancer at any time.

Trivia

 * The name of the White Heron Cup may be a reference to the heron laguz of Fire Emblem: Path of Radiance and Radiant Dawn. The heron laguz royals, who have white wings, have abilities equivalent to the Dancer class.
