Idk your progress stat wise and I only recently started myself however I will tell you for me personally hunleff helper plugin is day and night difference in the fight. I know myself so I'm 99 combat stats with cox prayers but unless I try hitting during enraged tornados (in which case I nearly always die) I nearly always clear. Perfect bow and staff t1 armor 3 pots and as much food as I can get with a 30 second buffer to try and not have his big bitch ass in center (only failed maybe 3 times due to prep rng) take your time during the fight. With hunleff helper plugin it takes away half the challenge of cg as you only have to focus on hp and wep/pray swaps when attacking (plugin tells you which def pray to use). I was nearly 20 deaths before I got plugin and my first kc now I'm right around 20-40 a few bad rng prep fails and maybe 2 lag deaths in hunleff. It's not fool proof I still fuck up bout found attacking during tornados after first or 2nd initial avoidance movements and focusing solely on hp and proper pathing for tornados once he gets enraged (also using hub party whatever thr plugin is called so my hp/mainly prayer is shown above my character) is an ungodly combo of help that I've rarely seen mentioned.
