Boss Rush excites summoners, but hey, hold your horses. It’s a mid-level Boss Rush event. It will be released as a side quest next month and will be focused on shards-based rewards. Take a quick look at the completion and exploration rewards:
3000 six-star shards, 8% Trier 5 Class Catalyst Crystals, and 12000 Tier 5 Basic Catalyst Fragments are the Major Rewards you can get.
Do we have a release date?
Not Exactly, should arrive around Women’s Day.
