Seriously, ever since the original Dark Souls, these freakish frogs have been the bane of our existence. On their own, the frogs don't pose a challenge to kill, but it's the incredibly annoying status they inflict that will make you want to tear your hair out in frustration.
Bed of Chaos has to be one of the most broken and unfair boss fights in the series. It's a gimmick boss that is almost impossible to beat without dying at least 2 times. Players must destroy the rings on both the left and right side, but the Bed of Chaos uses sweeping attacks that can one shot the player.
Inspired by ancient mesoamerican architecture and home to one of the four Lords, Lost Izalith plays a fairly important role in the events of Dark Souls. Unfortunately, it's one of the most annoying areas to traverse in the entire trilogy.
There shouldn't be any doubt that Pyromancer is the best class to start with. It comes with a hand axe, round shield, and pyromancy flame that is very helpful. This is the class for people who want to play Dark Souls for the first time or want to experience a hybrid of strength and deadly pyromancy.
The Asylum Demon is the very first boss of Dark Souls who essentially acts as the final enemy of the game's tutorial. It may not seem challenging to veteran players who have played a bunch of Souls-likes, but players going through Dark Souls for the first time may struggle quite a bit with this demon.
1 Dragon Slayer Ornstein & Executioner Smough - Dark Souls
Depending on which boss is slain first, the survivor will absorb his partner, giving him more damage with lightning or increased range. Dragon Slayer Ornstein and Executioner Smough are arguably the most challenging bosses in Souls-likes history.
Patches, whether he's Unbreakable, Trusty, or a Hyena, is the scum of the earth in any Dark Souls game. He notably appears in the first and third games and he's more than a troublemaker there.
The only person who can rob you of your sins in Dark Souls is the NPC character Oswald of Cairm. This guy can be found hanging out in the Bell Tower of the Undead Parish, after the defeat of the Bell Gargoyles. He will sell Absolution to you for a price.
Dark Souls is extremely hard from the get-go, even through its "tutorial" stage, because it doesn't hold your hand and it makes you loop, sometimes maddeningly, through areas you've already completed before. You also can't truly pause.
He's the fastest any boss has been in the original Dark Souls and is a new challenge not seen before. Artorias also buffs himself in the fight to increase his damage output just like the player would do.
