I started last month mid way through the vampire event. Currently I have 14 stars and have decided to give up until I have powered my troops.

My current plan is trying to get demon crystals to get spica- currently up to like 125 and powering up odette, bashira, yuyu and finally CCing Cloris. The best level I can currently commission is Fiery Oasis. Is there anything else I should be aiming to do with this time? I also have Sophie and often she seems to be a good lightning rod- but I feel like leveling her may take away XP I could send to my other ranged attackers.
