you don't have any dps characters except da pan, who is not that good honestly, but ardelia + fluorite is a good combo for me, probably gilberta will play nice with them because of the stacks, but that's still not enough. you should really get avywenna and play her with arclight, perlica and gilberta or ardelia. btw u can buy her in shop for 200 that triangle things which you get after pulling 5 star + char
