Heartopia Rainbow Event Guide: Doris Locations and Rainbow Bouquet Spots
The Heartopia Rainbow Event is a short, six-hour special weather window that starts at 6 PM server time, and the fastest way to make it worth your time is to check the in-game watch for the rainbow icon, grab Rainbow Bouquets for their 30-minute buff, then follow the rainbow to Doris in Whalefall Canyon before it vanishes.
