For 10 extra Wicket shards in Endor Escalation, you spend 900 crystals for another refresh. That’s 90 crystals per shard.
Wicket is now available in shipments for 80 crystals per shard, in bundles of 4 for 320, 8 for 640, and 16 for 1,280.
The event only comes around once a month. Why would anyone do the event refresh if they can get Wicket any time he comes around in shipments for cheaper? Just my thoughts.
