To be frank I've already beaten Dead Ringer years ago due to how short the fight usually is but thought I'd do it again and record it. On the other hand, I've procrastinated with Necrodancer 2 for a long time due to finding the fight not enjoyable as Coda, but at least Coda and other non-story characters can now freely fight any story specific boss without mods or co-op shenanigans ever since Synchrony came out.
I know most people don't read descriptions fully but for those that do, let me give you some extra details relating to what I wrote at the end of the video. I have gotten quite close to a legitimate Coda low% Conductor fight clear, I do believe it is actually beatable and I plan on making a huge high effort explanation video on it once I beat it since it involves so many silly strategies. It could easily be a 10 to 20 minute long video since I plan on commentating it and describing exactly how I did it, I'm even getting a custom thumbnail drawn for it since it is a huge deal for me! At the time of writing this description, nobody has done Coda low% Conductor without no beat mode and I partially want to be the world's first since I have slightly built up a reputation in the past for doing story mode bosses as Coda, so I feel inclined to do so.
