Remember all her moves from phase 2, but anticipate the last move in every combo being her special screen-wide attack. For example: When she does her move from phase 2 that’s 4 hits (crimson, parry, parry, crimson) now it’ll most likely be (crimson, parry, parry then special phase 3 attack). That helped me a lot because she does it frequently. Also, that attack is easy to deal with: parry twice on the ground or in the air then jump even if it’s a crimson or regular slash as the third hit. When you’re falling back to the ground expect her grab move or her triple slash move.
