Yup, it's a great buff. Even at NP1 with 1 curse she's not too far behind the free NP5 Quick Archers for damage. I just ran her upgraded version in the Halloween 90++ and she nearly clears it with a min damage roll, missing curse, and non MLB BG. I'm going to run her in some other 90++ to see just how good the farming can be. Mine is only NP1 so she probably won't be replacing my Lv 100 Kuro for farming, but it's always good to have more viable options. And she's always been very good for bosses so easy EX tier now.
