The Nameless King is a two phase boss fight, which basiclly means that the fight will change at a certain point. For Nameless King, the second phase starts after the King of the Storm is defeated. If this is a little confusing, let me explain. When a players enters the boss arena, the name that apears is King of the Storm, but the boss that apears is the Nameless King riding on a dragon/ bird thing. Now, I am not sure if the bird is the King of the Storm, or the Nameless King and the bird are the King of the Storm, but either way, most people just call the entier boss fight the "Nameless King boss fight."
The first thing I remember about the Nameless King boss fight, is actually what happends before I even entered the fight. To activate the boss the player must ring a bell. The bell will trigger a cutscene that shows storm clouds rolling in. When the cutscene finished, the environment got darker, rain had started falling, and there are storm clouds infront of the player. To be clear, the storm clouds are below the player, and on the ground. To get to the boss area, the player must walk across the clouds. Yes, WALK ACROSS CLOUDS. Unfortunetly, the player has to fight on clouds too. The fight against the Nameless King is one of the hardest in the game, and that's without cosidering the clouds. The cloud made fighting him harder because they made distence harder to gauge. I could not tell how fare I was from him the first couple of times I fought him. Maybe it was just me, or maybe it was caused by something else, but I am fairly certain that fighting on the clouds made judging distence more difficult then it needed to be.
Anyway, what about the fight it self? I a glad you asked, and if you didn't ... well I'll tell you anyway. I don't remember everything of cource, but I will tell you waht I do. Let's start with the first phase of the fight against the King of the Storm. One coolest part of the fight is when the Storm circles around the player and throws a lightning bolt. The cool part isn't the lightning, but dodging the lightning. In DS3 the player can lock there view onto an opponent to keep them in sight, so when the Storm flys around the player, the player's view will angle up making the action of dodging the bolt look cool, at least to me. There are some attacks on the other hand that are annoying to dodge. Sometimes Storm will fly up and hover there while it breaths fire directly downwards. This is annoying because more often then not, he will go out of sight, so I can't tell if he is just moving away from me or doing this attack. Also, this attack has a big aoe (area of effect), so I have to start running ASAP, or I will get hit by it. And is does a decent amount of damage. So overall, this attack is BS, but it is avoidable, so it's not total BS. The King of the Storm is a difficult enemy to say the least, but the Nameless King is worse.
When I first defeated the King of the Storm, I was happy that I finally defeated a boss that I had a decently difficult time defeating, until the cutscene started. In my experience, if a cutscene starts in a game like this, it almost always means that something unfortunate is about to happen, and unfortunetly, I was right. The Nameless King showed up and killed me fairly quickly. So, why did I die to Nameless so quickly? Is it because he has some difficult attacks? Well, yes, but also becasue I just finished fighting the Storm and as a consiquence, have low health. But hold on, it gets worse. If I don't defeat Nameless, I have to start all over. Which, as you may have guessed, means that I have to fight the Storm again just I have a shot at Nameless again. Now, I know what you may be thinking, "at least you can beat the Storm." I thought that too until I died to him two more times. And yes, I died to Nameless very quickly after beating Storm. As if fighting Storm over and over again wasn't bad enough, Nameless was no pushover either. In fact, I would say that Nameless is harder than Storm, which is saying something becasue I struggled with Storm. Anyway, I quit the game shortly after, but only for a few days. Once I was back in the game, I was ready to beat the boss ... bosses? Whatever, my point is that I was wrong. I had forgotten how to figth the boss during the break and die several more times. On the bright side, it didn't take me too long to get back into the swing of the game. After many more deaths, I finally beat the Nameless King with bearly any heath left ... and then a cutscene started. But luckly for me, this was one of those cutscene that did not end with me dying. Instead it was there just to signify the end of the fight. After fighting the Nameless King myself, I finally under stood why people consider him to be one of the most difficult bosses in DS3, but unfortunetly for me, he was not the most difficult.
