“Some new goods to keep an eye out for are a new mount, banner, masks, and some stylish costumes. You may hold up to three prophecies at a time and you can sell them to gain new prophecies if you’re struggling with a hard one. There are different levels of prophecy: normal, great, and special. The more normal prophecies you fulfill, the more likely you are to get a great prophecy. Special prophecies are quite rare and give better rewards, and you’ll get one of these each day the event is active as a login bonus! You can also earn anniversary costumes and a portrait decoration as rewards for completing challenges throughout the event.”
The event is already live for PC and console players, except for Switch players, where it’ll begin April 13th. There’s a staggered end for the festivities as well: April 21st on PC, April 22nd on PlayStation and Xbox, and April 27th for Switch.
