Priconne : March Clan Battles Day Four plus struggling in Dungeon 3 (Princess Connect RE:DIVE)

We got the first Wyvern sometime last night or this morning, so on to Wyvern #2. I have a few more Rank 8’s from grinding for CP for the Clan Battles. I can hardly wait till the mystery items become available to rank them up even further. How about you? How many Rank 8 do you have? What’s it like when 6 of your team need 20 x Angel Sword? (note: if only I knew the pain that was coming for Rank 9 and 10)
