The Artorias of the Abyss DLC for Dark Souls was notoriously convoluted to access for newer players, requiring them to quit and reload their game in a cove at Darkroot Basin behind the Hydra boss to even start the sequence to get to the DLC levels. However, returning players had a better idea of how to access the DLC before it released by discerning the location where the levels are accessed through the DLC’s trailer and certain NPC dialogue.

Every environmental object in Dark Souls has an associated damage and health value, with breakable objects having a defense value of 0, 3, 90, 199, or 999 and unbreakable objects having an HP of -1. The player is only capable of destroying objects with defense values of either 0 or 3 such as boxes or tables while certain objects like the breakable wall at Sen’s Fortress, or the raised platform above the Asylum Demon at the beginning of the game, have higher defense values and can only be destroyed by enemies or hazards.

Lost Izalith was originally going to be a swampy area like the bottom of Blighttown. However, FromSoftware didn't want it to be a swamp and so it was redesigned to be a lava field, but the team couldn't completely redesign the place the way they wanted to due to time constraints.

There are eight Titanite Demons in Dark Souls, but the one on the bridge connecting the Demon Ruins to Lost Izalith is the only one that respawns due to a typo in that Titanite Demon's event ID. However, it's unknown if this was an accident or a deliberate typo to remove a limit from upgrading weapons.

The character most commonly known as Snuggly the Crow or Sparkly the Crow is not a crow at all. She is actually a hawk named Hawk Girl and the more common names were actually created and propagated by fans.
