4 nightsister zombie shards from event
You get 4 shards from the “rare” event, you can only run the event once, and put a 1099 crystal pack in the store...lol

you can't clear the bonus tier? If you can, i'll advice you to always do the bonus tier, it rewards slightly more shards. This is also the 2nd time this event was live, and it will go live again. It takes rather long to 7 star them both, but it's completely free, you don't even need to spend energy.
