For a short time only, from 08:00 UTC, Friday May 13, to 08:00 UTC, Monday, May 16, they’re DOUBLING your odds of getting a Legendary Champion.
Before you take part in this event, consider the following:
There is an upcoming Fusion event. We can assume this global summoning boost will coincide with either a Champion chase, or summoning event/tournament. However, in the case that it doesn’t, it is advised that you do not open any shards during this global summoning boost event. Additionally, the next guaranteed summon will most likely require Sacred shards, and will take place not long after the fusion event ends. As such, you might want to conserve as many shards as possible, and only use enough during the upcoming fusion to collect the fusion Champions and nothing more.
