This footage is the second time I soloed Fallen Cazar with Noble (Forgot to record the first one). I'm currently writing a Google Doc breaking down boss difficulty in this game. To give my thoughts on Fallen Cazar, I'll just take an edited excerpt from that doc.
"Fallen Cazar is one of the most psychotic bosses I’ve ever encountered in any video game. Attempting to beat this guy is crazy; attempting to solo him is fucking ludicrous. Let’s break down his difficulty.
Fallen Cazar features some ridiculously hard combos and tons of new attacks. The new combos are some of the hardest to survive in any boss battle I’ve faced. Fat hitboxes, quick follow ups, and high damage. There are very little breaks in between and no room for error. Almost every move has some sort of exploding orb paired with it, forcing you to constantly be mindful of positioning.
And the new moves are extremely dangerous. Topaz bullets require you to pinwheel like BFS Kadee, ruby drill often requires 5 dodges to avoid. (4 at minimum) But worst of all is ruby cataclysm, which forces you to dash away from an expanding damage radius while simultaneously playing jump rope over lifedoom shockwaves. These shockwaves increase in size the further they move, you're only safety pocket is a tiny gap between the shockwaves and the radius.
Plenty of Cazar’s moves get superbuffed. Time rend now sweeps the entire map and one shots. The aggression radius explodes after the bullets close in, likely one shotting you. Time curse drains half of your stamina while applying slowness AND lifedoom. The last thing you want to happen is get hit by a curse wave and get murked by a follow up voidshatter.
Voidshatter has the potential to end your run. It now releases amethyst colliders with a massive explosion radius. Also, the voidshatter wave applies lifedoom. Also, the initial explosion radius gets buffed, requiring 4 dashes. ALSO, if you get hit by that initial explosion, you lose ALL OF YOUR LIVES. Don’t have enough stamina? That’s unfortunate, there’s fuck all you can do about it. If you’re lucky, you can let your stamina regen while Cazar shoots up for a very slight chance at making it out alive.
Seriously, stamina conservation is of utmost importance for this fight. The only viable classes are probably sword, noble, dancer, ember, and maybe sentry. Mace, radiant, and gladiator are out of question for this fight; that's not gonna happen. In some cases, it's more important to prioritize stamina over survival because of voidshatter. There’s also the funeral combo/finisher. It’s basically 3 minutes of Cazar spamming all of his moves. Most of it isn’t too dangerous if you’ve been consistently dodging everything else, but there are some ass clenching moments. These include triple time rend, triple aggression, back-to-back cataclysm, and triple ruby drill. You’re likely gonna have to sacrifice a life for triple aggression, you don’t have enough stamina to make it out of those back-to-back. Luckily it occurs right after triple time rend, so you can drag Cazar to the opposite end of the spawn to avoid aggression.
Since there is only one phase, you don't have to worry about learning anything later on. Once you learn him, it's still not gonna be easy. Like I said earlier, you must perform with little to no error. Keep the nerves in check, and you might have a chance at surviving this ridiculous fucking encounter."
