[pc] Promised Consort Radahn Help

[Help] [PC] I need help fighting consort radahn. not like tips *as i've tried HARD finding tips, with nothing succeeding* but as in an actual player who can help me. i've been using maxed out mimic tear and i think his name was sir ansbach? i've had around 20-30 tries so far on him with the best run having 1.8/4 of his health left. that was my second run, and i've had ZERO experiences like that since.

All i need is one player, good or bad, to help me. as long as Radahn isn't targeting me to the fullest while there's 2 other npc's, i'll be happy! this is my first ever post here. i may have misread the rules and this post may be posted incorrectly.

STATS are 60 vigor, 24 mind, 27 endurance, 22 strength, 49 dexterity, 42 intelligence, 42 faith and i'm currently working on arcane, but currently level 9.

For my equipment, i'm using full royal knight armour as my armour set. i am using nagakiba 25+ with flamespear ash of war, and for my right hand, it's gonna be hand of melania 10+ .

dragoncrest great shield 3+, pearldrake great shield 3+, erdtrees favor 2+ and great-jars arsenal are all my talismans.

i have 14 elixirs all in crimson. i have a 10+ mimic tear, 600 boiled crab, a psykick drink or whatever they were called, and torrent in my lower bar.

again, i may have made this post wrong! if so, please tell me what i need to fix!
