How to Get All Endings
Please note that information indicated here is for the original Demon’s Souls on the Playstation 3. We will update this page when Demon’s Souls Remake for the Playstation 5 is released.
There are two separate endings that you can unlock at the end of the game which are the good and bad ending. Which one you get depends on the choice that you make after defeating King Allant.
After the Maiden in Black finishes talking, simply turn around and walk away to unlock the good ending. This allows her to lull The Old One to sleep and lift the black fog. Having saved Boletaria, you become the new Monumental.
You will obtain the Maiden in Black’s Demon’s Soul which can be consumed to get 60,000 souls. It can also be traded for the powerful Soulsucker spell by talking to Yuria the Witch. Soulsucker instantly kills any single target except bosses but can only be used at extremely close range. It also has a considerably long cast time.
You can choose to kill the Maiden in Black to unlock the bad ending. Doing so condemns the world into ruin because of your lust of power, becoming its new ruler.
You will get the Beast Demon’s Soul which can be consumed to get 200,000 souls and the Red Eye Stone which lets other players summon you as a Black Phantom to engage in player-versus-player duels.
Which Ending Should You Get?
When playing for the first time, it is highly recommended to unlock the Good Ending first as it rewards you with a unique soul required to obtain the Soulsucker spell. On your subsequent playthroughs, you can choose to get the Bad Ending to get a large amount of souls.
