Below is my current Myrrh (+Atk -Def) set. I just summoned a +Def -Atk one. Based on her weapons effect, and the super bane, the -Def one is better. Should I merge into the +Def, or the +Atk?
49 atk is still fine plus with her special the higher def the better. Also def is a super bane -4 I would keep her as a tank that fishes out massive dmg on specials. Go with -atk +def is what I would do. She does have aether
Her weapon already gives her +3 Atk, which helps compensate for the bane. With +Def, her weapon also allows her to tank much better by preventing more follow-up attacks from occurring.
