Shamu/PSeyona Step-Up

No comment on the purchasability of the step-up. Please determine it for yourself. Here I will just tell you what the steps get you.
#Mythic Upgrade Box : 30 of any legendary material at random 
#Fantasy Upgrade Box : 10 of any immortal material at random, including some exploration materials. Worth it if you get the Immortal Cloth for mages, else meh. 
Will update with pics, and more details soon.
