Duped my 7-star Blade.
I'm happy that I duped him but I feel bad at the same time that I can’t use him because he can’t reach his full potential without his synergies. (This makes him useless in BG and when you are Questing GR and Dormamu/Mephisto is a burden)
Here is a simple idea that will make him great again. Remove all his Synergies and add those to his existing abilities.
