Top Ten Best Bosses in Dark Souls 2

In my opinion, one of the most underrated games out there. If you want to get into this series start here.
The Top Ten
1 Fume Knight

If you feel confident wearing the Full Havel's set or the smelter armor, this guy can one or two shot you depending on how low your vigor is and what playthrough it is. Right now I'm in New Game +11 he one shots me in full upgraded havel. He also goes straight into phase 2 if you are wearing any of velstadt's armor.

2 Burnt Ivory King

It's your army versus his. Make sure you find all the uncorrupted loyce knights before you drop into his arena.

3 Sir Alonne

An Honorable duel. Bow to him because he bows to you when you enter the boss room.

4 Looking Glass Knight

Cool looking knight that can summon npcs or actual players ( if you're online) to aide him in the fight. Beat him up using blunt weapons.

5 Sinh, the Slumbering Dragon

Another hard boss due to high damage output, and weapons breaking easily. Best use Bracing knuckle ring to slow weapon degradation, use a weapon with high durability( *Cough* Smelter hammer *Cough*), or use a lot of repair powder. Also staying behind works as well.

6 Darklurker

Deals no physical damage( I think) better use armor to strengthen you fire, dark, and magic resistances. Rings also help greatly.

7 The Pursuer

Fought in a lot of places.

8 Aava, The King's Pet

Awww snow kitty, that hits you like a pickup truck.

9 Lost Sinner

I suggest you beat the belfry gargoyles first to get a key. You'll brighten up the dark boss room by doing that.

10 Velstadt, the Royal Aegis

First time around he is hard to beat, but once you practice fighting against the enemies at Heide's tower of flame, he becomes slightly easier.
