Honestly its just the last boss speed toward the bells if you are doing it solo. I solo flawless up till boss with no problem, mechanics on final boss is not that hard. Enemies are a tad annoying but when you get to his damage phase i immediately kill the 2 middle bell bearers. 1 fusion, 1 witherhoard. See wheres hes going and im practically always jumping infront of him because he runs so fast i have to make him stop. Then i dont get the bell bearers cuz he stomps me around everywhere and boom. Dmg phase gone. Final boss is so bs when solo
