If players do not wish to get that particular reward, they can visit other players' worlds for a chance of getting a different box. After exchanging five boxes, players can open a "Mega Box O' Marvels."Rewards from the second Marvelous Merchandise event in January 2021 (Image via Nable, HoYoLab)Based on the event description, this Marvelous Merchandise will most likely follow the system of the last event.This means that it can be predicted that each box will contain 40 Primogems, while the Mega Box will contain 100 Primogems. So exchanging five boxes and obtaining the Mega Box will reward players with a total of 300 Primogems.Nice I love this event.
