I got lilia, adele, and another pegasus rider stella. People commented between claudia and lilia, well mine is: Lilia is more safer than claudia but with her skill claudia makes better lightning rod. I was thinking of doing castle retake map with lilia cus she have 15mr but a well timed claudia did better which had 20mr with her skill and very easily tanked lich, honestly u can tank it with 0 mr with a good healer but u get the point.
Adele is super hot and op, i recommend level up her immediately and aw her first, her damage is very good, dunno about war of magic stuff.
As for liddy, i couldnt find any use for my stella, yeah she got 5 sec aoe but i didnt even used it, i regret ccing her cus i got dahlia in later summons which is very badass and the second best of the valkyries
Cant say something about 4 and 5 cuz i dont have them. I found momiji pretty good, u can consider using her over kojuro if you not plan to use 2 samurai in the same time which is not recommended unless u got super powered healers.
