15 15. Dancer Of The Boreal Valley

Found in the Cathedral in High Wall of Lothric, opposite to the Vordt of the Boreal Valley fight, she’s a boss that no player can avoid due to being a required enemy to defeat in order to progress in the game. What makes her interesting is that she can be fought quite early on, when the player is still severely under-leveled for the battle.

However, more importantly, it’s her actual fighting style that makes her a formidable enemy. Her attacks have a strange timing, which will easily punish careless players. Without proper care, her combos are devastating. Perhaps the most terrifying aspect of facing her, however, is her infamous spinning attack which can melt a careless player’s health bar.

14 14. Demon Prince

In the Ringed City DLC, the Demon Prince is a required boss to fight in order to progress further. He’s found at the end of Dreg Heap, and marks the first boss fight of the DLC. The first phase will actually summon two demons, and depending on which one is killed first, the second phase will be somewhat easier.

Although outnumbered in the first phase, it’s better to play aggressive here and shorten the duration of the first fight. Killing the Demon In Pain First is usually recommended. In the second phase, the Demon Prince himself will rise, and fighting him will require more caution. His fire attacks are especially deadly, as they have the ability to one-shot a player.

13 13. Pontiff Sulyvahn

Found in Irithyll of the Boreal Valley, Pontiff is a mandatory boss that needs to be beaten in order to progress in the game. For any player that isn’t comfortable in their parrying skill, this fight is a headache. His combo attacks are particularly long, including long windups on attacks that can throw players off.

The second phase of the fight will include a clone of the Pontiff, which has a smaller health bar. That being said, the clone is still tough to deal with since the player is essentially outnumbered. Both the clone and the original will attack the player with the same attack, only the clone tends to move sooner.

12 12. Nameless King

In Archdragon Peak, the player can fight an optional boss battle by pulling a lever that rings a giant bell. This summons a storm, as well as the Nameless King himself, riding on a storm drake. While it doesn’t have much HP, it will lunge on the player, breathe fire and generally behave much like the Ancient Dragon.

The King himself will use a powerful lighting spear while airborne, and on the ground swing at the player. After the drake dies, the second phase begins against the King himself. He’s an extremely aggressive fighter, and if the player isn’t patient, one hit could put a serious dent into their health bar.

11 11. Slave Knight Gael

The Slave Knight is found in Filianore’s Rest at the end of the Ringed City DLC. As such, he’s considered the final boss of the Dark Souls series. Gael is an aggressive fighter from the get-go, with very long combos that can finish a player off quickly. The second phase begins when his HP is drained to a third, and he’ll start to use his crossbow along with more advanced moves as well as miracles.

The third phase starts at 40% of his health. This is the most chaotic part of the fight, where the arena will be covered with lightning strikes. He’ll gain the ability to teleport and perform long aerial combos, along with sending skull-shaped homing orbs towards the player.

10 10. Ancient Dragon

The Ancient Dragon is far from one of the most enjoyable fights in the Souls series. But that doesn’t stop it from being any less challenging. Unless you’ve dedicated the entirety of the game toward building strength, this massive beast can defeat most players in one shot. Therefore, a majority of this battle involves running away from the Ancient Dragon before you can get caught up in its fiery breath.

9 9. Gwyn, Lord Of Cinder

8 8. Darkeater Midir

Darkeater Midir is an optional boss who appeared in The Ringed City DLC for Dark Souls 3. Despite being one of the larger bosses in the game, this dragon is actually easier to fight head-on rather than simply going for his feet or tail.

7 7. Sister Friede And Father Ariandel

One of the hardest bosses in Dark Souls 3, Sister Friede and Father Ariandel appeared in the game’s first DLC.

6 6. Four Kings

Most Dark Souls’ battles require a lot of patience on the part of the player. But patience is definitely not a virtue when facing off against the Four Kings. This boss battle is a race, as the bosses spawn on a timer. Therefore, taking out one king before the next appears will greatly increase the chances of emerging victorious.

5 5. Fume Knight

Once again proving that some of the hardest bosses in Dark Souls are found in the DLC, Fume Knight is the final boss in Crown of the Old Iron King. There’s basically no margin for error when facing off against the Fume Knight, as many of his attacks can single-handedly drain the player’s health bar.

4 4. Knight Artorias

One of the most important characters in Souls lore, Knight Artorias’s reputation really proceeded him in this epic battle from the Dark Souls DLC. Having been corrupted by the Abyss, this fallen knight’s moves are often erratic and unrelenting.

3 3. Black Dragon Kalameet

In Souls games, sometimes the safest place when facing off against a giant four-legged boss is to stay directly underneath them. But Black Dragon Kalameet doesn’t let the player linger below him for very long. This intimidating dragon is fast and flighty.

2 2. Dragonslayer Ornstein and Executioner Smough

If you thought squaring-off against one Dark Souls boss was hard enough, try taking on two at once. This is exactly what happened during the halfway point of Dark Souls, where players must face the lightening-fast Dragonslayer Ornstein and the massively-overpowered Executioner Smough.

1 1. Manus, Father Of The Abyss

Like so many bosses in the Dark Souls series, how difficult you found Manus, Father of the Abyss will depend on a wide range of variables — including your character’s build and fighting style. But all things considered, Manus checks all the boxes of what makes for a challenging boss; he’s relentless, versatile, and extremely intimidating.
