Sekiro - base vit, charmless, demon bell, no skills/prosthetics/consumables. Run summary, tips, etc
And that's Sekiro main bosses + 3x Inner reflections done. Have been posting fights here but also put all fights in this playlist.
Very fun run. No skills/prosthetics/consumables makes the fights harder, but basically means you don't need to worry about anything that isn't fighting the bosses. No farming, no grabbing material, no managing resources, just get in the mix and deflect and attack.
I've done ER WL0/no aux, LoP EL10, and Khazan base level. I would put this run at about the same difficulty as ER WL0/no aux, and fight times were similar to my base game WL0/no aux fights (ER DLC fights are longer though). Generally speaking I'd say a minute of combat in Sekiro feels harder than a minute in Elden Ring (need to make more player decisions in the same amount of time) but your experience may vary.
My approach for all bosses was to try and attack relentlessly to limit their movesets to them reacting to my attacks. I think that's the way to go vs standing in the center of the arena and letting the boss initiate.
If you just go charmless/demon bell you can cut most of these fight times in half or even more. Yahariku sugar + divine confetti is very strong and will last about a minute, which is an entire phase of combat so you can reapply.
You will miss prosthetic a lot. Firecracker for Gyoubu, Shuriken for Butterfly, spear for ape, firecracker for duo ape, malcontent + flame umbrella for Demon of Hatred. FWIW I do think you owe it yourself to try and do Ape Duo without cheesing the brown ape because the paired AI they have is very unique (arena is a bit too snug though).
I didn't miss skills very much. After you train yourself that don't have mikiri you don't really miss it and it does allow bosses to do some follow up attacks you basically never normally see. Generally speaking it does punish you for being on the edges of arenas more because typically your next best move other than mikiri is dodging over deflect.
Worst part of the run was Gyoubu and then the Juzou the Drunk fight. Gyoubu, for me at least, is pretty hard to no hit. Juzou isn't hard but you just need like 20 minutes fighting him without ads to learn his moveset and killing the ads is very annoying. If I was doing it again I would have killed Genichiro first and then come back and done Butterfly.
Re: Inner Bosses. Isshin isn't too bad (just don't R1 when he's in neutral in phase 1) and Genichiro is basically the same. I fought Father a lot more difficult because of the mist raven spam.
If you're considering a run, good luck! I really enjoyed this one.
