Elden Ring : Putrid Crystalian Trio Boss Fight (RL1 / No Damage) 

I said I wouldn't do these guys. I wouldn't have done it if their AI didn't get nerfed, but after testing it once it felt very doable. The start is very chaotic if two or three of them attack at once, but afterwards they mostly stand back watching their friend die.
I'll never, ever do the pre-nerf version though, because it's awful.
