I actually managed to get 3 UR shield drops in under 10 runs. Guess my luck hasn't run completely dry yet. They're pretty neat too, it has 4 stats: HP, ATK, DEF and Crit. The values aren't really high but having 4 positive stats is real nice.

I'll probably just end up getting 1 of each exchangeable equip from both events as I need to save potions for next 2 events. Not even sure if I can grab the tickets.
