skill break mystery +2, i think it need 100 fragments of her to get +2 mystery. U c*so switch it to other mystery like Y+2 if u want. Just farm her fragment from elite instance. Dont use vial since it will reset other skill. If u wanna use vial , use it first, then use fragment. As for mystery of her, using fragments is a must so u can switch to other mystery skill if u want.
