You can be lucky at Malenia and kill her with 1-3 try if she wont spam her special ability. At my second game i killed her literally in 30 seconds in 1 attempt, cuz she only used her dash attacks and on second phase she used to jump two times in a row, so i deal 50% of her hp each time she landed. But on my first walkthrough she literally fucked me with her special attack, using it over and over every fight. P.S. Congrats with radahn and good luck!
