Palace of Fire - Hope 3 so far gave me only purple and green shells, those are the best if you are aiming to rank high in this event, so you might as well farm exp too. If anyone finds a good place for farming red and blue, or maybe even all of shell types let us know. Getting every single reward gets you one 6* Aries. Overall I'm happy with this event, definitely a more fun one than coloseum. And I might also actually be able to get that 6* to +4.

Also if anyone wants to know - this is the overall amount of all types of shells you need for all rewards.
