You receive rewards when you reach certain numbers of progress points. The rewards are listed in-game by tapping the "P" button on the event map, or on this wiki's Event page under the "Progress Points" table.

You can get progress points on the event map by advancing and winning normal/boss battles. The higher the area, the more progress points you get.
