The Lords of Cinder
Abyss Watchers
The Abyss Watchers are likely the first boss you will face. The fight consists of two phases. In the first phase additional Watchers will spawn. They can fight both the player and the main boss, depending on who is closest to them. In the second phase the first Watcher will be the only one you fight, however his attacks will be a lot stronger, harder to dodge and empowered with fire.
Aldrich, Devourer of Gods
Like most bosses in Dark Souls, this boss consists of two phases. Aldrich fights with both melee attacks and ranged sorceries. In the second phase he casts more spells and generally gets faster, making it a rough fight overall.
Yhorm the Giant
Yhorm, is as his name suggets, a giant. Being quite a bit smaller than him, you have to dodge his attacks cleverly. With regular weapons Yhorm does not take a lot of damage, but in the back of the room, near the throne, you can find the Storm Ruler. The storm ruler is a sword which special attack deals a lot of damage against Yhorm.
Lothric, Younger Prince
The fight starts out as a one on one, you have to fight the older prince, Lorian, first. He attacks with a sword and has the ability to teleport behind the player, making for some surprise hits. After the defeatin the older prince you will have to battle both Lorian and Lothric at once. Lothric is riding on Lorian's back, casting spells at you while his brother attacks you.
