The Lord of Cinder is dead !
Hell Yeah !
This maybe the first time I had that feeling of gratification, after beating a boss. Until now, when I beat a boss in a few tries, I would think: "no big deal. if I could beat him in 1-5 tries, he must have been easy". And if I beat a boss after 10+ tries, I never thought "hell yeah, I'm awesome". I would think "mmm, I must suck if it takes me so many times". Or "yeah, the only reason I could beat this boss is because I summoned an NPC". I never feel especially good after beating a boss.
But this is different. On my first play-through, I didn't do the correct questlines, so I couldn't summon the 2 NPCs. I couldn't kill the Lord of Cinder after 30 or maybe even 50 tries. His timing would always mess with my rolls. I would roll too quickly, or too late. I'd make it into the 2nd phase, and then die. I did kill Nameless King and Friede with that character. In my 2nd playthrough, I did the correct quests, summoned an NPC, and killed Nameless King on my 2nd try. Easy.
Today I was working in my garden. Fuck my neighbor, he's always complaining that I should trim my hedge. So this afternoon I was doing that. Not fun. Tired, sweaty, bloody (fuck blackberries). I took a 30min break. Check the news. Then I thought, "maybe I should do one try on Lord of Cinder. Just one". And he died ! Three sips of Estus left. Whoohoo !
Oh, now I think of it. It must be the new Chloranty Ring + 3. Without that new ring, I would not have been able to do it.
I still suck.

Edit: took a day off today, to finish working in my garden. During my first break I decided to check out Midir again, and see how hard my longsword was hitting. I'd been there only twice or so, just to see him, two weeks ago, when I was playing the Ringed City. On my first go today, unembered, I got him to 40%. He did something (dark magic) and killed me when I was under him, and had only 40% health. He definitely seems doable. Maybe I should respec, do phase 1 in melee, and phase 2 with Mercury Pestilance.
TLDR: Midir seems doable. He's gonna die.
