I recently played some Arcane Reborn (don’t ask why) and I found that the bosses in the game are really really badly designed.
First of all, the emerald captain fight. There are pirates all over the arena that have perfect pathfinding, and I mean perfect. No matter how you jump and run, they will always reach you. This is a problem with the developers trying to make them better by making them smarter, when in reality, npcs like this need to be stupid, considering how much damage they have. The actual boss is incredibly hard to actually fight, because the island is on the other side of the map, and there are super pirates all around her. At least in AA, you had the choice not to fight her, but in AR it’s a story quest.
There is the revamped theos fight. This one is very annoying, you have to travel across the map to reach him, and when you do he has homing attacks and everlasting burn debuffs. The problem with the burning debuffs is the fact that you need to jump into the sea to remove them, which makes you very vulnerable (AR changed the theos arena, so there are no water pools on the edges).
The next one is the angel boss fight. She can heal (meaning you have to kill her in one fight). She has extremely high damage, and can shoot through walls. You can probably see why this wouldn’t be fun.
Then there is the rupin fight, which is on a small island that is covered with very very thick fog. You need to be able to see to be able to fight, especially in AA. The island is also a large hill, so you often get stuck trying to jump up the cliffs.
I think one of the main problems with how they designed them is the way they try to make them really hard by giving them very high damage and very smart AI. This is not good, especially when you spawn on the other side of the map.
Also, I would like to point out that AA bossfights are also kind of bad, like the kairo bossfight, where you can’t defeat him by yourself until you are at least level 80, and you are expected to defeat him at level 40, you also need to go through a ton of npcs to get to him, so you end up having low health when you finally get to the arena. He also has invulnerability frames that you cannot predict or see. The only thing that AA bossfights had better were the spawn locations.
These bossfights also have the problem of unpredictable/unavoidable attacks.
Honestly, bossfights need to be fun before they are difficult. You need to be able to repeatedly retry with ease, and above all, you need to be able to predict their attacks.
Don’t get me wrong, I’m not just saying “AR bad”, I’m saying that there is room for improvement.
