My Top Ten Hardest Soulsbourne Boss Fights

Either they are a brutal yet fair boss fight that can be really fun, or they are an unfair encounter that you'll barely beat.
The Top Ten
1 Orphan Of Kos (Bloodborne)

He's fast, he hits fairly hard, and he has a massive health pool. You may need a hard hitting weapon, you still would die if you suck at dodging or parrying, but at least you will deal more damage.

2 Sister Friede (Dark Souls 3)

Phase 1- Just you and her
Phase 2- Just you, her, and Father Ariendel. A tad harder than phase 1
Phase 3- Jesus, could this bitch get any faster. I swear that she was a boss in Bloodborne, but they forgot to add her to the game so they added her to DS3

3 Ludwig the Accursed (Bloodborne)

Hits hard, I mean really hard. He can one shot you if you aren't careful.

4 Manus, Father Of The Abyss (Dark Souls)

Deals a lot of dark damage, so you're going to need that necklace, or be up close and dodge the hell out of some of those attacks. He can also combo attack the ever loving hell out of you.

5 Lud and Zallen, the King's Pets (Dark Souls 2)

This fight is ass and here's why. They stick these two snow cats that hit very hard and run around just to annoy you at the end of an area that has thunder gazelles and thick blizzards.

6 Lady Maria Of The Astral Clocktower (Bloodborne)

A fight that is very fun yet hard, but not as hard as the bosses that is harder than her.

7 Blue Smelter Demon (Dark Souls 2)

His attack speeds change a lot, so be prepared to dodge early or get hit.

8 Nameless King (Dark Souls III)

In the first phase you have a very sucky camera so don't lock on. Second phase introduces a fellow who hit somewhat hard and kinda fast. I don't know what else to say.

9 Black Dragon Kalameet (Dark Souls)

It was either this or Dark Eater Midir, but I chose this dragon because his attacks are harder to dodge.

10 Slave Knight Gael (Dark Souls 3)

A decent challenge, his standard attacks hit hard, but his AOE attacks hit even harder. His first phase is harder in my opinion.
