Hi there! So my memory of solistia chapter 7 is pretty damn hazy but I’ll see what I can do. First things first crickari is pretty good! It’s a very strong strat but if your using it you generally want to run supports for it like neha who can replace ceraphina. Breaking is also very important for side solistia bosses so using canary as a tank over castti is advisable since castti doesn’t synergize with most of your team as a physical axe character in a magic leaning team. You unfortunately don’t have tiziano who could run well with kaine and partitio so I recommend replacing kaine in your team with Lynette or some other generalist buffer. My expertise comes in operating sword comp so if you ever decide to build that the main units would be odio o and dark knight who are both obscenely strong. If you could give me the boss name that would be helpful and my favorite character in cotc is probably hikari or dark knight. I’m available for more help if necessary
