Breeding System

Yuliverse offers a breeding system that allows players to spend $ARG and $ART to breed two Yulis above level 30, resulting in a new mystery box. The rarity of the mystery box is determined by the quality of the parent Yulis, with a higher rarity of Yulis resulting in a greater probability of obtaining a high rarity mystery box. Each Yuli can only breed a maximum of five times, with at least a one-month interval between each breeding

Each Yuli can only breed a maximum of five times, with at least a one-month interval between each breeding. This system encourages players to carefully consider their breeding strategy and make strategic choices to maximize the value of their Yulis and the mystery boxes they obtain.

The probability relationship between the rarity of the mystery box and the rarity of the two breeding parties is shown in the figure below:
